DeTeWe ALIAN¶

DeTeWe (together with Fujitsu) was developing and selling a family of V5_Access_Multiplexers called ALIAN (Advanced Line Interconnection Access Network).

It is also sold as Fujitsu FSX2000 subscriber multiplexer.

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 (PWR-H) units
• Main Processor Unit (MPU-H)
• Network Management Interface (NMI) unit
• Time sLot Assignment (TSA) unit
• V5 Message Controller (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 (SLM15G)
• ISDN BRA subscriber line module (BRA12T)
• Trunkj or tributary E1 interconnection (E1B21, E1BU4)
