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.
Note
Access 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 3-2 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 3-1 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:
Note The Cisco ASR1000-SIP40 is not supported on the Cisco ASR1002 Router, Cisco ASR 1002-Fixed Router, and Cisco ASR 1002-X Router.

4-Port and 8-Port Fast Ethernet SPA Cables, Connectors, and Pinouts
The interface connectors on the 4-Port and 8-Port Fast Ethernet SPA are four or eight individual RJ-45 receptacles. You can use all interface connectors simultaneously. Each connection supports IEEE 802.3 and Ethernet 10/100BASE-T interfaces compliant with appropriate standards. Cisco does not supply Category 5 unshielded twisted pair (UTP) RJ-45 cables; these cables are available commercially.
Figure 3-8 shows the RJ-45 connector. Table 3-6 lists the pinouts and signals for the RJ-45 connector.

Note Referring to the RJ-45 pinout in Table 3-6, proper common-mode line terminations should be used for the unused Category 5 UTP cable pairs 4/5 and 7/8. Common-mode termination reduces the contributions to electromagnetic interference (EMI) and susceptibility to common-mode sources. Wire pairs 4/5 and 7/8 are actively terminated in the RJ-45 port circuitry in the 4-Port and 8-Port Fast Ethernet SPA.
The 4-Port and 8-Port Fast Ethernet SPA supports automatic MDI/MDIX crossover at all speeds of operation allowing the SPA to work with straight-through and crossover Ethernet cables. Depending on your RJ-45 interface cabling requirements, use the pinouts in Figure 3-9 and Figure 3-10.

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 3-13 shows the cable type for use with the XFP optical transceiver module on the 1-Port 10-Gigabit Ethernet SPA.
Note The 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 3-14 shows an XFP module and Table 3-8 shows the XFP module specifications.

SFP Module and Cabling Specifications for Gigabit Ethernet SPAs
The following sections describe SFP module specifications and cabling information for the Gigabit Ethernet SPAs:
SFP Module Specifications
The SFP module has a receiver port (RX) and a transmitter port (TX) that compose one optical interface. Table 3-15 , Table 3-16 , Table 3-17 , Table 3-18 , and Table 3-19 provide SFP module information and 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.
GLC-TE Modules
The 1000BASE-T SFP module (GLC-TE) sends bidirectional serial data over shielded and unshielded twisted pair, category 5 cables. Autonegotiation is not supported. It has a RJ-45 connector that can work in 10/100/1000BASE-T mode with SGMII host.
SFP Module Cabling and Connection Equipment
Table 3-17 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).

Note The 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.

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:
Note The 2-Port Gigabit Synchronous Ethernet SPA hardware is the same for all configurations of the product.
Table 3-21 describes key interface specifications on the 2-Port Gigabit Synchronous Ethernet SPA.

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.
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 bidirectional 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.

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 3-45 provides a matrix for the maximum number of channels supported on the DSP core and on SPA-DSP, and the complexity type:

The SPA-DSP supports transcoding for the codecs listed in Table 3-47 .
Table 3-47 SPA-DSP-Supported Transcoding Codec List

|
|
|---|---|
Features of SPA-DSP
Following are the features of SPA-DSP:
- Enhances ASR 1000 Series Router capabilities by providing DSP-based voice transcoding and transrating solutions.
- Translates one type of media stream (voice) to another type of media stream that uses different media encoding and decoding technologies.
- Enables translation between different packetization settings and provides dual tone multifrequency (DTMF) interworking.
- Provisions the configuration of SBC as either a Unified SBC or Distributed SBC with on-board DSPs or with a centralized DSP providing trancoding for multiple SBCs.
- Faceplates LEDs to indicate SPA status.
- Monitors voltage and temperature.
- Supports online insertion and removal (OIR).
SPA-DSP LED
SPA-DSPs have only one type of LED, which is the STATUS LED type, as shown in Figure 3-50.

The physical layer interface for the 24-Port Channelized T1/E1/J1 CEoP SPA is a customer-installed high-density connector. This connector has thumbscrews that should be screwed into the SPA when the cable is installed.
24-Port Channelized T1/E1/J1 CEoP SPA Cables and Connectors
The 24-Port Channelized T1/E1/J1 CEoP SPA requires a Cisco cable (part number CABLE-24T1E1J1), which is shown in Figure 3-54.

Cable Installation
One end of the cable has a 100-pin connector that plugs into the front of the 24-Port Channelized T1/E1/J1 CEoP SPA. Use the thumbscrews on either side of the connector to secure the cable to the SPA.
The other end of the cable has two 50-pin Telco connectors that can be attached to the rear of a
24-port RJ-45 patch panel. Both connectors are identical: one is for Transmit (TX) and the other is for Receive (RX). Figure 3-55 shows how the cable is connected between the 24-Port Channelized T1/E1/J1 CEoP SPA and the patch panel.

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:
– 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).
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.
