Board ID's ?

[Arnoldnt]

Hello people !

Just a quicky this time.

Does anybody know where I can get my hands on a List of Board ID's and Descriptions ( Brief) of what they do,

I've got the normal one sorted Eg .. 31, 59 , 77 etc
Just having a spot of bother finding about

Id's 22, 26, 28, 102, 108 ,96


Thanks in Advance

From ALEX:

CDU2. CD2 is the Charge Detection block responsible for selecting and counting meter signals being sent to the outgoing trunk circuit (exchange line) from the public exchange. Filter units are responsible for selecting metering pulses consisting of 12KHz or 16KHz bursts having durations and pauses of >100 milliseconds. Once filtered, the metering signals are sent to the detector.

The call metering pulses detected by the detector unit are stored in the data area supporting the trunk circuit.

There are two basic hardware configurations. The filter unit may either bridge the trunk line but offer no attenuation of the metering pulse towards the trunk unit, or provide attenuation to the metering pulses as they are transmitted towards the trunk unit. Metering signals selected in the filters, are sent to the detector. Different filter units may be used within the CD2 block allow detection of different market adaptations.


TLU23 is a private analogue external line circuit for E&M signalling. The board can be adapted for two- or four-wire connection, for different line impedances, for different transmission levels and for different voltages on the signalling wires.

TLU21 is a trunk circuit for incoming and outgoing loop call traffic from/to other PABXs. The board can be adapted for different line impedances, for different PROM sizes and for different resistance values in the current feed network.

ALU2. The function AL constitutes the system's interface to alarms and supervision equipment. The board ALU2 has 8 alarm inputs and 8 alarm outputs.

TMU/2. The printed board assembly Tone and Multi-party Unit (TMU) is a support-board in the Line Interface Module (LIM) of ASB 501 designed to provide tone receiver, tone sender, Music On Hold-input (MOH) and conference functions. The TMU can be initiated to handle A-law or u-law Pulse Code Modulation (PCM).

ELU31 is a DECT radio exchange board for connecting DECT radio base stations (RFP) to the ASB 501 04. ELU31 can connect up to eight DECT radio base stations and serve about 47 portable handsets at 0.2 Erlang/portable and 1 GOS.
ELU31 contains switches on board so that the channels to the base stations can be freely allocated.
