The 1- and 2-port T3 port adapters provide direct connectivity to T3 lines for full duplex communications at the DS3 rate of 44.736 MHz. With integrated line interface units (DSUs) that allow DS3 lines to be directly terminated on a Cisco router, these interfaces provide a more cost effective solution than a combined HSSI interface plus external DSU solution.
These products feature interoperability with DS3 DSUs from major vendors including Digital Link, Larscom, and Kentrox. New enhanced versions, PA-T3+ and PA-2T3+ offer greater interoperability with these third party DSUs.
Key Features:
DS3 connectivity with no external DSU required
Subrate DS3 support
Scrambling support
High density: Up to 4 DS3 ports per Cisco 7500 slot
Unframed, C-Bit, or M13 framing (software selectable)
B3Z Line Coding
DS3 FEAC channel support
