Pre-owned, used and refurbished Cisco WS-SVC-CMM-6T1

The 6-port T1 and E1 port adapters (including the WS-SVC-CMM-6T1) have onboard digital signal processor (DSP) resources that allows the user to connect the interfaces to the public switched telephone network (PSTN) or private branch exchanges (PBXs) through T1 Channel Associated Signaling (CAS)/E1 R2 or T1/E1 ISDN Primary Rate Interface (PRI). The DSP resources on the port adapters provide packetization, echo cancellation, fax relay, tone detection and generation, concealment, and jitter buffers making the WS-SVC-CMM-6T1 Communication Media Module an ideal voice-feature enhancement for the Catalyst 6500 Switch series and the Cisco 7600 Router Series.
