SuperNode SE link interface shelf

The SNSE LIS is part of the SuperNode SE configuration. In this arrangement, the SNSE LIS is collocated with a DMS-bus (MS), 16kbyte ENET, CM, and SLM hardware in a single frame. By virtue of the proximity to the MS, there is no need to provide a fiber or DS30 interface with the SNSE LIS. The F-bus interface hardware (rate adapter) is integrated into the MS. The SNSE LIS shelf supports a maximum of 14 ASUs and services. To provision beyond this maximum, either a separate SSLPP or LPP must be added to the office.

Figure 46 on page 184 provides an overview of the SNSE LIS configuration with its inter-shelf F-bus connection to the MS.
