Subscriber Line Group (SLG) in ISDN
Digital outside lines that are to have the same traffic characteristics can be
grouped into subscriber line groups (SLG) in the public network (e.g. several basic
accesses with the same DDI block).
An SLG must also be recreated in the PBX. For this the network connections of
the outside lines of an SLG must be allocated to the same trunk group (see Fig.
2.30).
A subscriber line group can consist of basic accesses, primary rate accesses or indi-
vidual B-channel groups of primary rate accesses (also mixed).
