Time-division multiplex channels for peripheral boards

The following table lists the maximum number of time-division multiplex channels that the dif-

ferent boards require. A distinction is made here between:

static time-division multiplex channels

Time-division multiplex channels are subject to static assignment in trunk boards. This en-

sures that all incoming calls can be processed.

dynamic time-division multiplex channels

Time-division multiplex channels are subject to dynamic assignment in subscriber line

modules. Channels are seized for each call and released afterwards. This means that the

current number of time-division multiplex channels required is determined by the number

of active stations.

Restrictions for using the TMDID board

The TMDID board only uses the first half of a PCM segment. Consequently, a max-

imum of 64 channels is available on each PCM segment for TMDID-specific static

time-division multiplex channels.

To guarantee that the system operates without blocking when using the TMDID, the

boards on a PCM segment must not require more than the 64 static time-division

multiplex channels.

Examples for a PCM segment:

2 x TMDID + 1 x DIU2U = 64 static time-division multiplex channels = approved

1 x TMDID + 1 x TMC16 + 1 x DIU2U = 72 static time-division multiplex channels

= unapproved equipment

1 x TMDID + 2 x SLMO2 = 8 static and 96 dynamic time-division multiplex chan-

nels = approved equipment
