Configuring the SHDSL LIM
The Stinger SHDSL 48-port and 72-port line interface modules (LIMs) support
single-pair high-speed digital subscriber line
(SHDSL) mode. In addition, four wire
support combines the bandwidth of two ports to double the available bandwidth.
When an SHDSL LIM is installed in a Stinger slot, the Stinger chassis connects the
LIM to a line protection module (LPM), which provides the physical connections for
incoming lines. The 48-port SHDSL LIM provides 48 SHDSL interfaces per LIM. The
72-port SHDSL LIM provides 72 SHDSL interfaces per LIM.
Introducing the SHDSL LIMs
Stinger units support SHDSL LIMs with 48 and 72 ports, each of which is available in
two versions. Table 1-1 list the SHDSL LIM models and the supported platforms.
