About ATM Uplink with Enhanced Gigabit Ethernet Interface Modules

The Catalyst 8540 supports two ATM uplink with enhanced Gigabit Ethernet interface modules: the OC-3c and the OC-12c. These interface modules consist of two port adapters that are attached to a carrier module. The port adapters are not hot swappable, but the interface module as a whole is hot swappable. The ATM OC-3c uplink or the OC-12c uplink port adapter resides on the left side of the interface module and the one-port enhanced Ethernet Gigabit port adapter resides on the right side. The OC-3c has 64 KB of routing table memory. The OC-12c has 64 KB or 256 KB of routing table memory.

Note   Both port adapters within these interface modules must have matching routing table memory. For example, if the ATM OC-12c uplink 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 25-1 identifies the maximum number of interface ports supported in each system.

Figure 25-1 shows an ATM uplink with enhanced Gigabit Ethernet interface module.

Connections Supported

This combination of the OC-3c and the OC-12c port adapters provides an Ethernet port for connection to, or within, a LAN and an ATM uplink port to a metropolitan-area network (MAN). For more information on the enhanced Gigabit Ethernet port adapter, see "Two-Port Enhanced Gigabit Ethernet Interface Modules."

JATE Approval

The ATM uplink with enhanced Gigabit Ethernet interface module meets the Japan Approvals Institute for Telecommunications Equipment (JATE) approval. See Table 25-2 for JATE approval details for the interface module.

Cabling ATM Uplink with Enhanced Gigabit Ethernet Interface Modules

This section describes supported cabling configurations for the ATM uplink with enhanced Gigabit Ethernet interface module.

Note   "Connectors and Connector Pinouts," lists cabling requirements.

Interface Module Connectors

The ATM OC-3c uplink port adapter supports 155-Mbps multimode or single-mode intermediate-reach fiber connections. It supports Fast EtherChannel operation, uses SC-type connectors, and has built-in ACL functionality.

The ATM OC-12c uplink port adapter supports 622-Mbps multimode or single-mode intermediate-reach fiber connections. It supports Fast EtherChannel, SC-type connectors, and has built-in ACL functionality. (See Figure 25-2.)
