Introduction and Specifications
T1 Network Application
The SRM-6 multiplexer is shown below in a typical T1 application with the SC553 DSU and the
SCM. On the DTE side, the SRM-6 acts as a DCE, multiplexing up six DTEs into one aggregate.
On the DCE side of the SRM-6, communication with the co-located DSU is configured to one of
two aggregate data rates: 56 or 64 Kbps. Local and remote sites are connected over the 4-wire, T1
line. Management is conducted via a craft or LAN/Telnet connection to the SCM.
