Port Adapter Overview

The PA-POS-2OC3 provides two Packet-over-SONET (POS) ports in a single port adapter slot. The two ports function as either dual independent OC-3c/STM1 ports or a single port with automatic protection switching (APS). The PA-POS-2OC3 is used as a direct connection between the supported router or switch platform and external networks.

The PA-POS-2OC3 fits into a single port adapter slot on the Cisco 7204VXR router, Cisco 7206VXR router, Cisco 7201 router, Cisco 7301 router, Cisco 7304 PCI port adapter carrier card in a Cisco 7304 router, Cisco 7401ASR router, Cisco 7500 series routers (Cisco 7505, Cisco 7507, Cisco 7513), and the Cisco 7600 series routers with FlexWAN or Enhanced FlexWAN.


Note The Cisco 7206VXR router can be used as a router shelf in a Cisco AS5800 universal access server.

SONET/SDH Overview

The POS specification addresses the use of PPP encapsulation over SONET/Synchronous Digital Hierarchy (SDH) links. SONET is an American National Standards Institute (ANSI) standard (T1.1051988) for optical digital transmission at hierarchical rates from 51.840 Mbps (STS-1) to 2.5 Gbps (STS-48) and greater. SDH is the international standard for optical digital transmission at hierarchical rates from 155.520 Mbps (STM-1) to 2.5 Gbps (STM-16) and greater.

Because SONET/SDH is by definition a point-to-point circuit, PPP is well suited for use over these links. PPP was designed as a standard method of communicating over point-to-point links.

SONET is an octet-synchronous multiplex scheme that defines a family of standard rates and formats. The basic rate for POS is that of STS-3c/STM-1, which is 155.520 Mbps. The available information bandwidth is 149.760 Mbps, which is the STS-3c/STM-1 Synchronous Payload Envelope (SPE), the payload portion of the SONET frame into which the octet-oriented user data is mapped. (Octet boundaries are aligned with the SPE octet boundaries.) For the SPE with the Cisco PA-POS-2OC3, section, line, and path overhead are removed.

The International Telecommunications Union Telecommunication Sector (ITU-T) defines a series of SDH transmission rates beginning at 155.520 Mbps, as follows:

SONET 1
SDH Equivalent

STS-3c2

STM-12

STS-12c

STM-4c

STS-48c

STM-16c

1 ANSI-defined SONET specifications.

2 Supported by the PA-POS-2OC3.


Despite the name, SONET is not limited to optical links. Electrical specifications have been defined for single-mode fiber, multimode fiber, and CATV 75-ohm coaxial cable. The PA-POS-2OC3 allows transmission over single-mode and multimode optical fiber. Transmission rates are integral multiples of 51.840 Mbps, which can be used to carry T3/E3 bit-synchronous signals.

The following transmission multiples are currently specified and commonly used:

STS-3c—155.520 Mbps (the PA-POS-2OC3 conforms to STS-3c)

STS-12c—622.080 Mbps

STS-48c—2,488.320 Mbps

Single-mode or multimode fiber-optic cables capability

For information on the single-mode and multimode cables to use with the Cisco PA-POS-2OC3 port adapter, see the "Cables and Connectors" section.

Interface Specifications

The physical layer interface for the PA-POS-2OC3 is Optical Carrier-3 (OC-3c), the specification for SONET STS-3c and SDH STM-1 transmission rates), and the PA-POS-2OC3 is designed to comply with Packet-over-SONET specifications. The PA-POS-2OC3 provides two 155.520-Mbps Packet OC-3 network interfaces for all supported platforms.

Each PA-POS-2OC3 has two duplex LC-type receptacles that allow connection to single-mode or multimode optical fiber. (For more information on the optical fiber cables you use with this port adapter, see the "Cables and Connectors" section.)

Packet data is transported using Point-to-Point Protocol (PPP) and is mapped into the STS-3c/STM-1 frame. The encapsulations used add approximately half the number of bytes of transport overhead as that involved with ATM using ATM Adaptation Layer 5 (AAL5) and line card control (LCC) Subnetwork Access Protocol (SNAP) encapsulations.

The PA-POS-2OC3 interface is compliant with RFC 1619, PPP over SONET/SDH, and RFC 1662, PPP in HDLC-like Framing. The PA-POS-2OC3 supports RFC 1619 PPP-over-SONET/SDH encapsulation, and provides support for SNMP agent v1 (RFC 1155-1157), and Management Information Base (MIB) II (RFC 1213).

OC-3 Optical Fiber Specifications

The OC-3 specification for optical fiber transmission defines two types of fiber: single-mode and multimode. Within the single-mode category, two types of transmission are defined: intermediate reach and long reach. Within the multimode category, only short reach is available.

Modes can be thought of as bundles of light rays entering the fiber at a particular angle. Single-mode fiber allows only one mode of light to propagate through the fiber, and multimode fiber allows multiple modes of light to propagate through the fiber.

Multiple modes of light propagating through the fiber travel different distances depending on the entry angles, which causes them to arrive at the destination at different times (a phenomenon called modal dispersion); therefore, single-mode fiber is capable of higher bandwidth and greater cable run distances than multimode fiber. Table 1-1 lists nominal OC-3 optical parameters for single-mode and multimode optical fiber transmission.


Note If the distance between two connected stations is greater than the maximum distances listed, significant signal loss can result, making transmission unreliable.


Table 1-1 lists the OC-3 optical parameters.

MIB II (RFC 1213); POS MIB support is available with Cisco IOS Release 12.0

Encapsulation Method Support

The following encapsulation methods are supported by the Cisco PA-POS-2OC3:

RFC 1619 Point-to-Point Protocol over SONET/SDH

We recommend that you refer to the Internet Draft Enabling Transparency for the PPP over SONET/SDH Mapping, which is recognized by the Internet Engineering Task Force (IETF) and Internet Engineering Steering Group (IESG) as an approved addendum to RFC 1619.

Using Statistics to Estimate Link Loss and Power Budget

Statistical models more accurately determine the power budget than standard worst-case methods. Determining the link loss with statistical methods requires accurate knowledge of variations in the data link components. Statistical power budget analysis is beyond the scope of this document. For further information, refer to ITU-T standards and your equipment specifications.

The following publications contain information on determining attenuation and power budget:

The following conditions must all be met before the PA-POS-2OC3 is enabled:

The PA-POS-2OC3 is correctly connected and receiving power.

The host system software supports the PA-POS-2OC3.

If any one of these conditions is not met, or if the initialization fails, the ENABLED LED does not come on.

Cables and Connectors

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 OC-3-equipped routers back to back.


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


The PA-POS-2OC3 provides 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.)


Note For maximum cable lengths between stations, see Table 1-1. Single-mode and multimode optical fiber cables for the PA-POS-2OC3 are not available from Cisco Systems; they are available from commercial cable vendors.


The PA-POS-2OC3 has two duplex LC-type receptacles. For SONET/SDH 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).

Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-POS-2OC3 in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on a PA-POS-2OC3 installed in a router maintain the same address regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the first number in the interface address changes to reflect the new port adapter slot number.

Interfaces on a PA-POS-2OC3 installed in a VIP or FlexWAN module maintain the same address regardless of whether other interface processors or modules are installed or removed. However, when you move a VIP or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect the new interface processor or module slot.


Note Interface ports are numbered from left to right starting with 0.


The following subsections describe the interface address formats for the supported platforms:

1 Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).

2 Port adapter slot 0 can accept the Port Adapter Jacket Card if an NPE-G1 or NPE-G2 are installed, but becomes slot 5 on a Cisco 7204VXR router when a port adapter is installed or slot 7 on a Cisco 7206VXR router when a port adapter is installed.

3 Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).

4 Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.


Cisco 7200 VXR Routers Interface Addresses

In Cisco 7200VXR series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 4 for the Cisco 7204VXR, and slot 6 for the Cisco 7206VXR. Port adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller—if present.) See Figure 1-4

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a PA-POS-2OC3 is installed in slot 1 and the ports are to be two dual independent ports, the interface addresses would be 1/0 and 1/1.

Cisco 7200 VXR Routers with the Port Adapter Jacket Card Interface Addresses

With an NPE-G1 or NPE-G2 installed, port adapter slot 0 of Cisco 7204VXR router or Cisco 7206VXR router can accept the Port Adapter Jacket Card. When the Port Adapter Jacket Card resides in port adapter slot 0, the port adapter in the Port Adapter Jacket Card is in port adapter slot 5 on the Cisco 7204 VXR router, or port adapter slot 7 on the Cisco 7206 VXR router. See Figure 1-5

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a PA-POS-2OC3 is installed in a Port Adapter Jacket Card in the slot formerly known as slot 0 on a Cisco 7204VXR router, but now known as slot 5 and the ports are to be two dual independent ports, the interface addresses would be 5/0 and 5/1(slot 5 and interface port 0 and 1). If a PA-POS-2OC3 is installed in a Port Adapter Jacket Card in the slot formerly known as slot 0 on a Cisco 7206VXR router, but now known as slot 7, the interface addresses would be 7/0 and 7/1 (slot 7 and interface port 0 and 1).

Cisco 7201 Router Interface Addresses

In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-6.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a PA-POS-2OC3 is installed in a Cisco 7201 router and the ports are to be two dual independent ports, the interface addresses would be 1/0 and 1/1.

Cisco 7301 Router Interface Addresses

In the Cisco 7301 router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-7.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a PA-POS-2OC3 is installed in a Cisco 7301 router and the ports are to be two dual independent ports, the interface addresses would be 1/0 and 1/1.

Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses

In the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the module slot number. See Figure 1-8.

The interface address is composed of a two-part number in the format module-slot-number/interface-port-number. See Table 1-3. For example, if a PA-POS-2OC3 is installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3 and the ports are to be two dual independent ports, the interface addresses would be 3/0 and 3/1.

Cisco 7401ASR Router Interface Addresses

In the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered as slot 1. See Figure 1-9.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-3. For example, if a PA-POS-2OC3 is installed in a Cisco 7401ASR router and the ports are to be two dual independent ports, the interface addresses would be 1/0 and 1/1.

Cisco 7500 Series Routers VIP Interface Addresses

In Cisco 7500 series routers, port adapters are installed on a versatile interface processor (VIP), which installs in interface processor slots 0 through 12 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter slot 0 or 1) on the VIP. See Figure 1-10, Figure 1-11, Figure 1-12, and Figure 1-13.

The interface address for the VIP is composed of a three-part number in the format interface-processor-slot-number/port-adapter-slot-number/interface-port-number. See Table 1-3.

The first number identifies the slot in which the VIP is installed (slot 0 through 12, depending on the number of slots in the router).

The second number identifies the bay (port adapter slot) on the VIP in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the VIP.

The third number identifies the physical port number (interface port number) on the port adapter. The port numbers always begin at 0 and are numbered from left to right. The number of additional ports depends on the number of ports on the port adapter. The PA-POS-2OC3 is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a PA-POS-2OC3 is installed in a VIP in interface processor slot 3, port adapter slot 1, and the ports are to be two dual independent ports, the interface addresses would be 3/1/0 and 3/1/1.


Note Although the processor slots in the seven-slot Cisco 7507 and the thirteen-slot Cisco 7513 chassis are vertically oriented and those in the five-slot Cisco 7505 are horizontally oriented, all Cisco 7500 series routers use the same method for slot and port numbering.


Cisco 7600 Series Routers FlexWAN Module Interface Addresses

In Cisco 7600 series routers, port adapters are installed in a FlexWAN or Enhanced FlexWAN module, which installs in module slots 2 through 13 (depending on the number of slots in the router). The port adapter can be installed in either bay (port adapter bay 0 or 1) on the FlexWAN or Enhanced FlexWAN module. See Figure 1-14, Figure 1-15, Figure 1-16, and Figure 1-17.

The interface address is composed of a three-part number in the format module-slot-number/port-adapter-bay-number/interface-port-number. See Table 1-3.

The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot 2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are generally numbered from top to bottom, starting with 1. The Cisco 7609 is the exception with slots numbered right to left, starting with 1.

The second number identifies the bay of the FlexWAN module in which the port adapter is installed (0 or 1). The bays are numbered from left to right on the FlexWAN module.

The third number identifies the physical port number on the port adapter. The PA-POS-2OC3 is a dual-port port adapter, therefore the port can be 0 or 1.

For example, if a PA-POS-2OC3 is installed in the FlexWAN module, which is inserted in module slot 3, port adapter bay 0, and the ports are to be two dual independent ports, then the interface addresses of the port adapter would be 3/0/0 and 3/0/1 (module slot 3, port adapter bay 0, and interfaces 0 and 1).
