Cisco NM-1HSSI High Speed Serial Interface Network Module

Cisco NM-1HSSI High Speed Serial Interface Network Module / Line Card (T3 / DS3) for Cisco 2600XM Series, 2691, 2800, 2811, 2821, 2851, 3640, 3700 Series, 3725, 3745, 3800 Series, 3825, 3845 - New Pull

Cisco recommends a maximum of one NM-1HSSI in a 2691, 2800,3725, or a 3825 and a maximum of two NM-1HSSIs in a 3745 or 3845.

The High Speed Serial Interface (HSSI) is a single port, network module interface that supports speeds up to 52 Mbps over a Wide Area Network. The HSSI network module for the 3600 requires an external T3/E3 CSU for connectivity to the WAN, or can be used in a back-to-back configuration, without the requirement for an external CSU. For use in the Enterprise or Service Provider environment; the HSSI network module can be used for point-to-point connections, Frame-Relay services, or used with inverse multiplexers to distribute your bandwidth over multiple T1/E1 lines.
