h2. ALIAN Shelves

ALIAN systems are built from _shelves_, each shelf hosting slide-in modules/components.  A shelf has slots 1 .. 23, whereas 18+19, 20+21 and 22+23 are double-wide slots.

Shelves come in two configurations: CMS (_Common Management Shelf_) and EXP (_Expansion Shelf_). The CMS and the EXP shelf are identical shelves. Their function is determined

by the plug-in units which are fitted to the shelves.

The CMS accomodates the following common units:

* Power Supply ([[DeTeWe_ALIAN_PWR-H|PWR-H]]) units

* Main Processor Unit ([[DeTeWe_ALIAN_MPU-H|MPU-H]])

* Network Management Interface (NMI) unit

* Time sLot Assignment ([[DeTeWe_ALIAN_TSA|TSA]]) unit

* V5 Message Controller ([[DeTeWe_ALIAN_V5MC|V5MC]]) unit

* System Interface Panel (SIP)

* Back Wiring Board (BWB)

A CMS can be used stand-alone.  Alternatively it can act as primary for EXP expansion shelves.

Each CMS and EXP shelf can then contain a number of termination modules, such as:

* POTS Subscriber Line Module ([[DeTeWe_ALIAN_SLM15G|SLM15G]])

* ISDN BRA subscriber line module ([[DeTeWe_ALIAN_BRA12T|BRA12T]])

* Trunkj or tributary E1 interconnection ([[DeTeWe_ALIAN_E1B21|E1B21]], E1BU4)
