104 Cabinet modular hardware

Single-shelf bus

The message switch is a hub for the communication between the switch's
components. The MS occupies the upper shelf of the SCC and is equipped
with cards on the front and corresponding paddleboards on the rear. The
cards share a common bus with the paddleboards.

Cooling unit

The cooling unit provides forced-air ventilation for the equipment housed
in the SCC.

Link interface

The Link Interface Shelf (LIS) is a single-shelf Link Peripheral Processor
(LPP) capable of supporting 12 Application Specific Units (ASUs). An
example of an ASU is the Link Interface Unit (LIU) for CCS7 applications.
The 12 ASUs supported by the LIS are in addition to the two LIUs that can
be provisioned with the ENET shelf for CCS7 applications.
If additional ASUs are needed, external LPP cabinets may be added. The
SuperNode SE system supports external LPPs up to the full physical
capability of the SuperNode SE message switch.

Enhanced Network

The Enhanced Network (ENET) shelf provides up to 16K ENET channels
on two planes, provisionable in 4K increments. The shelf can also be
provisioned with two LIUs, which can be used for CCS7 links.

Frame Supervisory Panel

The FSP controls alarms in the cabinet.

Power requirement

The SuperNode SE cabinet is powered by either the Meridian Cabinet
Auxiliary Module phase 3 (MCAM3). Both supply -48 V DC power to the
SuperNode SE cabinet. The power supply option selected is based on
the lineup configuration chosen by the user. For details on SuperNode SE
