About Packet-over-SONET Uplink with Enhanced Gigabit Ethernet Interface Modules

The Packet-over-SONET uplink with enhanced Gigabit Ethernet interface module consists of two port adapters attached to a carrier module. The port adapters are not hot swappable, but the interface module as a whole is hot swappable. The Packet-over-SONET OC-12c uplink port adapter resides on the left side of the interface module and the one-port enhanced Gigabit Ethernet port adapter resides on the right side. It is available with 64 KB or 256 KB of memory. Routing tables use this memory.

Note   Both port adapters within this interface module must have matching routing table memory. For example, if the Packet-over-SONET OC-12c POS port adapter has 64 KB of routing table memory, the enhanced Gigabit Ethernet port adapter must have 64 KB of routing table memory for the interface module to function properly.

Interface Ports Supported

Table 26-1 identifies the maximum number of interface ports supported in each system.

Figure 26-1 shows a Packet-over-SONET uplink with enhanced Gigabit Ethernet interface module.

Connections Supported

The packet-over-SONET uplink with enhanced Gigabit Ethernet interface module provides an Ethernet port for connection to, or within, LANs, and a POS uplink port for connection to an ISP or MAN. For more information on the enhanced Gigabit Ethernet port adapter, see the "About Two-Port Enhanced Gigabit Ethernet Interface Modules" section.

JATE Approval

The packet-over-SONET uplink with enhanced Gigabit Ethernet interface module meets the Japan Approvals Institute for Telecommunications Equipment (JATE) approval. See Table 26-2 for JATE approval details for the interface module.

Cabling Packet-over-SONET Uplink with Enhanced Gigabit Ethernet Interface Modules

This section describes supported cabling configurations for the packet-over-SONET uplink with enhanced Gigabit Ethernet interface module.

Interface Module Connectors

The packet-over-SONET OC-12c uplink port adapter supports 622-Mbps single-mode intermediate and long-reach fiber connections. The packet-over-SONET OC-12c uplink port adapter is a serial link, uses SC-type connectors, and has built-in ACL functionality. (See Figure 26-2.)
