Checking Hardware and Software Compatibility

To check the minimum software requirements of Cisco IOS software with the hardware installed on your router, Cisco maintains the Software Advisor tool on Cisco.com. This tool does not verify whether SIPs or SPAs within a system are compatible, but it does provide the minimum Cisco IOS requirements for individual hardware modules or components.


NoteAccess to this tool is limited to users with Cisco.com login accounts.


To access Software Advisor, click Login at Cisco.com, type “Software Advisor” in the SEARCH box, and click GO. Click the link for the Software Advisor tool.

Choose a product family or enter a specific product number to search for the minimum supported software release needed for your hardware.

Bandwidth Oversubscription

Oversubscribing the bandwidth limit recommendations of a router can result in decreased or degraded performance. For this reason, it is important to determine the amount of bandwidth used by the SPAs on the router and verify that the total bandwidth used by all SPAs does not exceed the recommended bandwidth limit of the router.

Table 1-2 provides information about the bandwidth for each port (per-port bandwidth) on a SPA and the cumulative bandwidth (total bandwidth) for all ports available on the SPA.

Cisco ASR1000-SIP10 Oversubscription Guidelines

The total available bandwidth in your router ultimately depends on the features that you have enabled, and the combination of hardware installed. This section describes some of the basic guidelines that you can use to plan for a possible oversubscription on the Cisco ASR1000-SIP10.

Each Cisco ASR1000-SIP10 supports 4 single-height SPAs. The chassis models of the Cisco ASR 1000 Series Aggregation Services Routers support a different maximum number of SIPs as follows:

  • Cisco ASR 1002 Router, Cisco ASR1002-Fixed Router, and Cisco ASR1002-X Router—1 integrated SIP
  • Cisco ASR 1004 Router — 2 SIPs
  • Cisco ASR 1006 Router — 3 SIPs

Each Cisco ASR1000-SIP10 has a 10 Gbps link to the Embedded Services Processor (ESP). Therefore, there is an aggregate bandwidth limit—the sum of the total SPA bandwidth installed in the SIP—of 10 Gbps per SIP. This limit can be exceeded with the installation of some combinations of SPAs. See Table 1-1 for individual SPA bandwidth values. This aggregate bandwidth is then subject to the maximum bandwidth limitations of the ESP (5, 10, or 20 Gbps) depending on the ESP model installed.

Cisco ASR1000-SIP40 Oversubscription Guidelines

The total available bandwidth in your router ultimately depends on the features that you have enabled, and the combination of hardware installed. However, this section describes some of the basic guidelines that you can use to plan for a possible oversubscription on the Cisco ASR1000-SIP40.

Each Cisco ASR1000-SIP40 supports:

  • Four half-height (¼ rate or full rate or combination) SPAs with upto 24 ports per SPA
  • Two full-height (¼ rate or full rate or combination) SPAs with upto 48 ports per SPA
  • Combination of two half-height and one full-height SPAs that do not exceed 96 ports

Warning Double-wide SPAs are not supported on Cisco ASR1000-SIP40.


The chassis models of the Cisco ASR 1000 Series Aggregation Services routers support a different maximum number of Cisco ASR1000-SIP40 as follows:

  • Cisco ASR 1006 Router — three SIPs
  • Cisco ASR 1013 Router — six SIPs

NoteThe Cisco ASR1000-SIP40 is not supported on the Cisco ASR1002 Router, Cisco ASR 1002-Fixed Router,and Cisco ASR 1002-X Router.


1-Port and 3-Port Clear Channel OC-3 ATM SPA Overview

The 1-Port and 3-Port Clear Channel OC-3 ATM SPA is a single-height SPA that installs into one SIP subslot. The 1-Port and 3-Port Clear Channel OC-3 ATM SPA with small form-factor pluggable (SFP) optical transceiver modules provides SONET and SDH network connectivity with a per-port bandwidth of 155.52 Mbps.

The following sections describe the 1-Port and 3-Port Clear Channel OC-3 ATM SPA:

1-Port and 3-Port Clear Channel OC-3 ATM SPA LEDs

The 1-Port and 3-Port Clear Channel OC-3 ATM SPA has three types of LEDs: two LEDs for each port on the SPA and one STATUS LED, as shown in Figure 1-1.

1-Port and 3-Port Clear Channel OC-3 ATM SPA Interface Specifications

The physical layer interface for the 1-Port and 3-Port Clear Channel OC-3 ATM SPA is Optical Carrier-3 (OC-3), and the data link layer is designed to comply with ATM specifications. The 1-Port and 3-Port Clear Channel OC-3 ATM SPA provides up to four 155-Mbps OC-3 network interfaces for all supported platforms.

1-Port and 3-Port Clear-Channel OC-3 ATM SPA Cables and Connectors

The 1-Port and 3-Port Clear Channel OC-3 ATM SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber connection (see Figure 1-2).

Each SPA port accepts an SFP module with a duplex LC-type receptacle that allows connection to single-mode or multimode optical fiber.

Figure 1-2 SFP Optics Module

 

The SFP optical transceiver modules used with the 1-Port and 3-Port Clear Channel OC-3 ATM SPA provide the following optical fiber options:

  • Multimode—155-Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1)

Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.

  • Single-mode—155-Mbps, OC-3 optical fiber (SONET STS-3c or SDH STM-1)

Use a single-mode optical fiber that has a modal-field diameter of 8.7 ± 0.5 microns. (Nominal diameter is approximately 10/125 microns.)

For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see Figure 1-3) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).

Use a single-mode (for intermediate-reach or long-reach configurations) or multimode optical fiber cable to connect your router to a network or to connect two 1-Port and 3-Port Clear Channel OC-3 ATM SPA-equipped routers back-to-back.

Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between them.

1-Port 10-Gigabit Ethernet SPA XFP Optical Transceiver Modules, Connectors, and Cables

The 1-Port 10-Gigabit Ethernet SPA supports the following types of optical transceiver modules:

  • Single-mode short-reach (SR) XFP module—XFP-10GLR-OC192SR
  • Single-mode intermediate-reach (IR) XFP module—XFP-10GER-OC192IR
  • Single-mode very-long-reach (ZR) XFP module—XFP-10GZR-OC192LR

Cisco qualifies the optics that are approved for use with its SPAs. The above-listed small form-factor pluggable modules (XFPs) are the only optical transceiver modules qualified for use.

Use a single-mode optical fiber that has a modal-field diameter of 8.7 ±0.5 microns (nominal diameter is approximately 10/125 microns) to connect your router to a network.

Figure 1-13 shows the cable type for use with the XFP optical transceiver module on the 1-Port 10-Gigabit Ethernet SPA.

Figure 1-13 LC-Type Cables

 


NoteThe 40-pin connector on the 1-Port 10-Gigabit Ethernet SPA is used for resilient packet ring (RPR) connections


XFP Connections

The XFP-10GLR-OC192SR, XFP-10GER-OC192IR, and XFP-10GZR-OC192LR modules include an optical transmitter and receiver pair integrated with Clock and Data Recovery (CDR) integrated circuits. The XFP modules provide high-speed serial links at the rate of 10.3125 Gbps (10 Gigabit Ethernet) on single-mode fiber (SMF). The transmit side recovers and retimes the 10-Gbps serial data and passes it to a laser driver. The laser driver biases and modulates a 1310-nm or 1550-nm laser, enabling data transmission over SMF through an LC connector. The receive side recovers and retimes the 10-Gbps optical data stream from a photo detector transimpedance amplifier and passes it to an output driver.

See the label on the XFP module for technology type and model. Figure 1-14 shows an XFP module and Table 1-8 shows the XFP module specifications.

SFP-GE-S Modules

The 1000BASE-SX (short-wavelength) module operates on standard multimode fiber-optic link spans of up to 1640 feet (500 m) on 50/125um multimode fiber (MMF) and 984 feet (300 m) on 62.5/125um MMF.

SFP-GE-L Modules

The 1000BASE-LX/LH (long-wavelength/long-haul) module interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 6.2 miles
(10 km) over single-mode fiber (SMF) versus the 3.1 miles (5 km) specified in the standard.

SFP-GE-Z Modules

The 1000BASE-ZX (extended-wavelength) module operates on ordinary single-mode fiber-optic link spans of up to 49.7 miles (80 km). Link spans of up to 62.1 miles (100 km) are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. (Premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation and less dispersion.)

The 1000BASE-ZX module must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The 1000BASE-ZX module does not operate correctly when coupled to multimode fiber, and it is not intended to be used in environments in which multimode fiber is frequently used (for example, building backbones or horizontal cabling).

The 1000BASE-ZX module is intended to be used as a Physical Medium Dependent (PMD) component for Gigabit Ethernet interfaces found on various switch and router products. It operates at a signaling rate of 1250 Mbaud, transmitting and receiving 8B/10B encoded data.

When shorter lengths of single-mode fiber are used, it may be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver. Use the following guidelines:

  • Insert a 10-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is less than 15.5 miles (25 km).
  • Insert a 5-dB inline optical attenuator between the fiber-optic cable plant and the receiving port on the 1000BASE-ZX module at each end of the link whenever the fiber-optic cable span is equal to or greater than 15.5 miles (25 km) but less than 31 miles (50 km).

SFP-GE-T Modules

The 1000BASE-T SFP module (SFP-GE-T) is compliant with IEEE 802.3:2000 and plugs into a standard Gigabit Ethernet SFP module port. It operates on standard Category 5 wiring and has an RJ-45 connector. The SFP-GE-T maximum cabling distance is 328 feet (100 m).

The SFP-GE-T is hot-swappable. Autonegotiation is not supported. The SFP-GE-T module supports 10/100/1000 speeds, which must be explicitly configured using the speed command. Only full-duplex mode is supported, which must be configured using the duplex full command.

SFP Module Cabling and Connection Equipment

Table 1-17 provides cabling specifications for the SFP modules that can be installed on the Gigabit Ethernet SPAs. Note that all SFP ports have LC-type connectors.

The minimum cable distance for the SFP-GE-S is 6.5 feet (2 m), and the minimum link distance for the SFP-GE-Z is 6.2 miles (10 km) with an 8-dB attenuator installed at each end of the link. Without attenuators, the minimum link distance for the SFP-GE-Z is 24.9 miles (40 km).

8.Dispersion-shifted single-mode fiber-optic cable.


NoteThe 1000BASE-ZX SFP modules provide an optical power budget of 21.5 dB. You should measure your cable plant with an optical loss test set to verify that the optical loss of the cable plant (including connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed with a 1550-nm light source.

The 2-Port Gigabit Synchronous Ethernet SPA is a half-height SPA with these LEDs:

  • SPA status LED
  • Line status LED - A bi-color, surface-mount, right-angle LED dedicated to each SFP, RJ-45 and coax connector to indicate port status
  • Debug LED

2-Port Gigabit Synchronous Ethernet SPA Interface Specifications

The 2-Port Gigabit Synchronous Ethernet SPA is compatible with the 2-Port Gigabit Ethernet SPA on all platforms and provides additional services of clock frequency and time of day synchronization. The2-Port Gigabit Synchronous Ethernet SPA uses new technologies such as Synchronous Ethernet (SyncE), ESMC, and IEEE1588v2.

However, the 2-Port Gigabit Synchronous Ethernet SPA supports only optical interfaces. As a result the 2-Port Gigabit Synchronous Ethernet SPA does not support multiple line speeds (10/100/1000 Mbps) on the 2-Port Gigabit Ethernet SPA.

Synchronous Ethernet is a layer 1 technology which delivers a very accurate frequency reference, but it doesn't address time synchronization. IEEE1588v2 defines a Precision Time Protocol (PTP), which distributes accurate timing information (both clock frequency and time of day) over packet networks. 2-Port Gigabit Synchronous Ethernet SPA hardware supports IEEE1588v2, either as a client or server. The 2-Port Gigabit Synchronous Ethernet SPA has these hardware capabilities to support the 1588v2 protocol stack:

  • Classification and forwarding of 1588v2 protocol packets.
  • Hardware time stamping.

Note The 2-Port Gigabit Synchronous Ethernet SPA hardware is the same for all configurations of the product.

Power Supply

The 2-Gigabit Synchronous Ethernet SPA extracts 18.854 watts maximum. The actual Lab measurements at room temperature result in only around 10.5 watts maximum.

Standards Compliance

The 2-Port Gigabit Synchronous Ethernet SPA complies with these standard specifications:

  • ITU-T G.8261 (2008) specifications for SyncE support on ethernet interfaces.
  • ITU-T G.8262 (OPTIONS 1 AND 2) for platform timing support and performance.
  • IETF TICTOC telecom profile support for performance.
  • ITU-T G.8261, G.8262, G.823, G.824, G.825, O.171, and O.172 for clock jitter and wander specifications.

2-Port Gigabit Synchronous Ethernet SPA Cables and Connectors

SFP Optics Module

The 2-Port Gigabit Synchronous Ethernet SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in each port.

Figure 1-21 SFP Optics Module

 

Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between the two of them.

BITS Interface

The BITS/SSU is a bi-directional interface implemented on the 2-Gigabit Synchronous Ethernet SPA. It relays a clock to an SSU and in return receives a clock without the wander. This interface also allows the 2-Port Gigabit Synchronous Ethernet SPA to be a system resource for older platforms that are not BITS capable.

2-Port, 4-Port, and 8-Port OC-3c/STM-1 POS SPA Overview

The 2-Port and 4-Port OC-3c/STM-1 POS SPA is a single-height SPA that installs into one SIP subslot. The 2-Port and 4-Port OC-3c/STM-1 POS SPA with small form-factor pluggable (SFP) optical transceiver modules provides SONET and SDH network connectivity with a per-port bandwidth of 155.52 Mbps. The 2-Port and 4-Port OC-3c/ST-1 POS SPA operates at quarter rate. The 8-Port OC-3c/STM-1 POS SPA operates at half rate.


NoteWhen SFP modules are replaced, the SPA interface retains any previously defined configurations. These configurations include settings for IP address, clock source, loopback, CRC, and POS flags.


For more information about SPAs and their compatibility with SIPs and modular optics, see the “SIP and SPA Compatibility” section.

The following sections describe the 2-Port and 4-Port OC-3c/STM-1 POS SPA:

2-Port and 4-Port OC-3c/STM-1 POS SPA LEDs

The 2-Port and 4-Port OC-3c/STM-1 POS SPA has three types of LEDs: two LEDs for each port on the SPA, and one STATUS LED, as shown in Figure 1-22.

2-Port and 4-Port OC-3c/STM-1 POS SPA Interface Specifications

The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-3c/STM-1 line rates (155.52 Mbps).

Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]), and is mapped into the STS-3c/STM-1 frame.

The 2-Port and 4-Port OC-3c/STM-1 POS SPA interface complies with the following RFCs:

  • RFC 1662, PPP in HDLC-like Framing
  • RFC 2427, Multiprotocol Interconnect over Frame Relay
  • RFC 2615, PPP over SONET/SDH

2-Port and 4-Port OC-3c/STM-1 POS SPA Optical Transceiver Modules and Cables

The 2-Port and 4-Port OC-3c/STM-1 POS SPA uses a small form-factor pluggable (SFP) optical transceiver module installed in each port for SONET and SDH single-mode and multimode optical fiber connection (see Figure 1-23).

Cisco qualifies the optics that are approved for use with its SPAs. The 2-Port and 4-Port OC-3c/STM-1 POS SPA supports the following types of optical transceiver modules:

  • Multimode (MM) SFP module—SFP-OC3-MM
  • Short-reach (SR) SFP module—SFP-OC3-SR
  • Intermediate-reach (IR) SFP module (15 km)—SFP-OC3-IR1
  • Long-reach (LR) SFP module (40 km)—SFP-OC3-LR1
  • Long-reach (LR) SFP module (80 km)—SFP-OC3-LR2

Figure 1-23 SFP Optics Module

 

The SFP optical transceiver modules used with the 2-Port and 4-Port OC-3c/STM-1 POS SPA provide the following optical fiber options:

  • Multimode—155-Mbps, OC-3c/STM-1 optical fiber (SONET STS-3c or SDH STM-1)

Use a multimode optical fiber that has a core/cladding diameter of 62.5/125 microns.

  • Single-mode—155-Mbps, OC-3c/STM-1 optical fiber (SONET STS-3c or SDH STM-1)

Use a single-mode optical fiber that has a modal-field diameter of 8.7 ± 0.5 microns. (Nominal diameter is approximately 10/125 microns.)

For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see Figure 1-24) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).

Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to connect your router to a network or to connect two 2-Port and 4-Port OC-3c/STM-1 POS SPA-equipped routers back-to-back.

Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between them.

2-Port, 4-Port, and 8-Port OC-12c/STM-4 POS SPA Overview

The 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA is a single-height SPA that installs into one SIP subslot. For the OC-12 SPAs, any given channel can be configured as either OC-3 or OC-12, so the per-port bandwidth can be either 155.52 Mbps or 622.08 Mbps respectively, depending on the customer configuration.


NoteWhen SFP modules are replaced, the SPA interface retains any previously-defined configurations. These configurations include settings for IP address, clock source, loopback, CRC, and POS flags.


The 8-port OC-12c/STM-4 POS SPA is a full-rate SPA; therefore, it can only be installed in subslots 1 or 2 of the SIP. The 2-Port OC-12c/STM-4 POS and 4-Port OC-12c/STM-4 POS SPAs are half-rate SPAs.

The following sections describe the 2-Port, 4-Port, and 8-Port OC-12c/STM-4 Multirate POS SPA:

2-Port, 4-Port, and 8-Port Clear-Channel T3/E3 SPA Interface Specifications

The framer processes incoming and outgoing T3 (cbit, m13/m23, and unframe) and E3 (g751, g832, and unframe) frames. The framer operates at T3/E3 line rates (44.736 Mbps/34.368 Mbps) depending on the mode in which it is configured.

Packet data is transported with a user-configurable encapsulation (such as Point-to-Point Protocol [PPP] or High-Level Data Link Control [HDLC]), and is mapped to T3 and E3 frames. The encapsulations add transport overhead to the packet of data frames before transporting, and are stripped when a packet is transported to the far end.

The T3/E3 SPA interface is compliant with ANSI and Telco standards. The interface also provides support for Management Information Base (MIB) RFC 2496 and T1.231.

2-Port, 4-Port, and 8-Port Clear-Channel T3/E3 SPA Cables and Connectors

The interface connectors on the 2-Port, 4-Port, and 8-Port Clear-Channel T3/E3 SPA are 75-ohm coaxial 1.0/2.3 cables that are specific to the T3/E3 SPA, with one connector and cable for transmit (TX) and one for receive (RX).

The following cables can be used with the 2-Port, 4-Port, and 8-Port Clear-Channel T3/E3 SPAs and any other T3/E3 SPAs:

  • CAB-T3E3-DINBNC-F (T3 or E3 Cable, DINBNC female connector, 10 feet)
  • CAB-T3E3-DINBNC-M (T3 or E3 Cable with DINBNC male connector, 10 feet)
  • CAB-T3E3_DINDIN-F (T3 or E3 Cable with DINDIN, female-female connectors, 10 feet)

The following cables can be used with the 2-Port and 4-Port Clear-Channel T3/E3 SPA and not with the 8-Port Clear-Channel T3/E3 Serial SPA. The cables have BNC connectors on one end and the 1.0/2.3 RF connectors on the other end.

  • CAB-T3E3-RF-BNC-M (T3 or E3 Cable, 1.0/2.3 RF to mini BNC-Male, 10 feet
  • CAB-T3E3-RF-BNC-F (T3 or E3 Cable, 1.0/2.3 RF to mini BNC-Female, 10 feet)
  • CAB-T3E3-RF-OPEN (T3 or E3 Cable, 1.0/2.3 RF to BNC-Open end, 10 feet)

NoteThe Cisco cable part numbers are 72-4124-01 (with male BNC end) and 72-4131-01 (with female BNC end).

1-Port Channelized STM-1/OC-3 SPA Interface Specifications

The framer processes incoming and outgoing SONET or SDH frames. The framer operates at OC-3c/STM-1 line rates (155.52 Mbps).

Packet data is transported with a user-configured encapsulation (such as Point-to-Point Protocol [PPP]), and is mapped into the STS-3c/STM-1 frame.

The 1-Port Channelized STM-1/OC-3 SPAinterface is compliant with RFC 1619, PPP over SONET/SDH , and RFC 1662, PPP in HDLC-like Framing . The 1-Port Channelized STM-1/OC-3 SPA also provides support for SNMP v1 agent (RFC 1155–1157), and Management Information Base (MIB) II (RFC 1213).

1-Port Channelized STM-1/OC-3 SPA Cables and Connectors

The 1-Port Channelized STM-1/OC-3 SPAuses a small form-factor pluggable (SFP) optical transceiver module installed in the port for SONET and SDH single-mode and multimode optical fiber connection (Figure 1-44).

Figure 1-44 SFP Optics Module

 

The SFP optical transceiver modules used with the 1-Port Channelized STM-1/OC-3 SPA provide the following optical fiber options:

  • Multimode—155-Mbps, OC-3c/STM-1 optical fiber (SONET STS-3c or SDH STM-1)

Use a multimode optical fiber that has a core or cladding diameter of 62.5/125 microns.

  • Single-mode—155-Mbps, OC-3c/STM-1 optical fiber (SONET STS-3c or SDH STM-1)

Use a single-mode optical fiber that has a modal-field diameter of 8.7 ± 0.5 microns. (Nominal diameter is approximately 10/125 microns.)

For single-mode and multimode optical fiber connections, you can use either a duplex LC-type cable (see Figure 1-45) or two simplex LC-type cables, one for transmit (TX) and one for receive (RX).

Use single-mode (for intermediate- or long-reach configurations) or multimode optical fiber cable to connect your router to a network or to connect two 1-Port Channelized STM-1/OC-3 SPA-equipped routers back-to-back.

Long-range SFP optical transceiver modules (for long-reach configurations) cannot be connected back-to-back without using an attenuator between the two of them.

Cisco WebEx Node for ASR 1000 Series Overview

The Cisco WebEx Node for Cisco ASR 1000 Series SPA (also referred to as the Cisco WebEx Node SPA) is a double-height SPA that improves the functionality of WebEx meeting services. The traffic between the enterprise network and the WebEx Data Center is decreased, greatly reducing Internet bandwidth requirements.

Each Cisco WebEx Node SPA can be configured to perform either web conferencing or voice and video conferencing but not both features on the same SPA. The Cisco WebEx Node SPA provides a virtual service engine interface (with a minimum bandwidth of 2.5 GB) to handle the TCP/IP traffic for all services running on the SPA.

Cisco WebEx Node SPA LEDs

The Cisco WebEx Node SPA has three LEDs and one button, as shown in Figure 1-49.


NoteThe covered port on the faceplate near the STATUS LED is disabled and not intended for customer use.

Cisco DSP SPA for ASR 1000 Series Overview

To provide voice transcoding and transrating functionalities on Cisco ASR 1000 Series Routers, Cisco SPA-DSP (also referred to as SPA-DSP) has been introduced from Cisco IOS XE Release 3.2S. This section provides information about the need for a DSP SPA, and an overview of the SPA-DSP. It contains the following topics:

Understanding the Need for SPA-DSP

The growth of Internet has increased not only in terms of transmitting data, but transmitting voice and video over Internet as well. Although the growth of Internet has been exponential, the implementation of the process to transmit voice and video is challenging. Voice is transmitted over internet using a specific codec from a pool of supported codecs. To provide decoding and encoding from one type of codec to another type, interoperability is needed. The SPA-DSP has been introduced mainly to provide voice transcoding and transrating capabilities.

SPA-DSP Overview

The Cisco DSP SPA for Cisco ASR 1000 Series Routers is a half-height SPA that provides voice transcoding and transrating functionalities for media streams using different codecs. For example, translating a media stream that has been encoded using G.711 into G.729, it requires Digital Signal Processor (DSP). The SPA-DSP is a service SPA, and does not have any external physical interfaces. The SPA-DSP works in conjunction with the Session Border Controller (SBC) application to provide voice transcoding capabilities. The SPA-DSP can be installed in either SIP-10 or SIP-40 in any of the slots.

Each SPA-DSP comprises of seven SP2603 DSP chips having a total of 21 DSP cores (three DSP cores per SP2603). Based on the complexity of codec (low, medium, high), the density or maximum number of channels supported per DSP core and maximum channels supported per SPA-DSP are defined. Table 1-45 provides a matrix for the maximum number of channels supported on the DSP core and on SPA-DSP, and the complexity type:

RJ-45 Cable Pinouts

T1 lines from individual subscribers are attached to the RJ-45 connectors on the front of the 24-port patch panel. Each RJ-45 port accommodates an individual T1 subscriber line.

Pins 1 and 2 and 4 and 5 of the RJ-45 connectors are used for the 24-port CEoP SPA’s Transmit (TX) and Receive (RX) signals. Depending on how the cable is installed between the SPA and its patch panel (rear), the RJ-45 connectors operate as follows:

  • If the TX cable lead is connected to Transmit on the patch panel and RX is connected to Receive:

The SPA’s TX signals are transmitted on RJ-45 pins 1 (ring) and 2 (tip).

The SPA’s RX signals are received on RJ-45 pins 4 (ring) and 5 (tip).

  • If the TX cable lead is connected to Receive on the patch panel and RX is connected to Transmit:

RJ-45 pins 1 and 2 are used for the SPA’s RX signal.

RJ-45 pins 4 and 5 are used for the SPA’s TX signal.

Patch Panel Cabling

If you are connecting two 24-Port Channelized T1/E1/J1 CEoP SPAs to each other, you must cable both the SPA’s patch panels together using a T1 crossover cable or a T1 straight through cable. The type of cable you use (crossover or straight through) depends on how the CEoP SPAs are cabled to their patch panels:

  • If both the CEoP SPAs are connected to their patch panels in the same manner (TX to Transmit and RX to Receive, or TX to Receive and RX to Transmit), use a T1 crossover cable to connect the patch panels to each other.
  • If both the CEoP SPAs are connected to their patch panels in a different configuration (TX to Transmit and RX to Receive on one SPA, and TX to Receive and RX to Transmit on the other SPA), use a T1 straight through cable (standard RJ-45 patch cable) between the patch panels.
