Cisco PA-MC-2T3

The PA-MC-2T3+ is a single-width port adapter that provides two T3 interface connections using BNC connectors. (See Figure 1-1.) 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.
