New and Changed Information

PA-GE Gigabit Ethernet Port Adapter

Platforms: Cisco 7200 series routers

The single port Gigabit Ethernet Port Adapter (PA-GE) provides a Gigabit Ethernet connection for the

Cisco 7200 series router. This port adapter, which offers moderate performance, is suitable for campus,

enterprise edge and wide-area network (WAN) aggregation applications. When used on the campus, the

Cisco 7200 series router with the PA-GE connects the enterprise WAN to the Gigabit Ethernet campus

backbone. At the enterprise edge, the PA-GE connects the WAN to the Gigabit Ethernet campus

backbone. When the Cisco 7200 series router is used for WAN aggregation, the PA-GE provides

intra-pop connectivity between the router and high-speed WAN core devices, such as the Cisco 12000

series router. The PA-GE may be inserted into any open port adapter slot on Cisco 7200VXR routers.

PA-MC-T3+

Platforms: Cisco 7200 series and Cisco 7500 series routers

The PA-MC-2T3+ is a single-width port adapter that provides two T3 interface connections using BNC

connectors. Each T3 interface can be independently configured to be either channelized or

unchannelized. A channelized T3 provides 28 T1 lines multiplexed into the T3. Each T1 line can be

configured into one or more serial interface data channels.

An unchannelized T3 provides a single serial interface data channel that may be configured to use all

of the T3 bandwidth or a fractional portion of it. This mode is compatible with several vendors of

fractional (subrate) DS3 data service units (DSUs).

The PA-MC-2T3+ has the following features and physical characteristics:

• Supports both channelized and unchannelized operations.

• Transmits and receives data bidirectionally at the T3 rate of 44.736 Mbps.

• Conforms to relevant specifications for DS3 (Digital Signal Level 3) circuits.

• Supports RFC 1406 and RFC 1407 (CISCO-RFC-1407-CAPABILITY.my). For RFC 1406, Cisco

supports all tables except the FarEnd table.

For more information see the PA-MC-2T3+ Multichannel T3 Port Adapter Installation and

Configuration guide.
