IPECS Release 5
Feature Description & Operation 5.0
2-94
2.46 IP SYSTEM DECT
Description
iPECS supports office building mobility employing Digital European Cordless Technology (DECT).
LG Nortel’s DECT Base stations (GDC-400B) connect to the Wireless Telephone Interface Module
(WTIM). The WTIM manages up to eight (8) base stations and up to 3 WTIMs may be linked to
provide a DECT coverage zone with transparent handover. Within the Zone, DECT handsets (GDC-
400H) can roam and maintain an uninterrupted communications link to iPECS features and
resources through the base station to the WTIM. Additional zones can be created to the maximum
number of WTIMs allowed for the system, see Table 1.2-1.
For further information on installation and operation of the IP System DECT solution, refer to the IP
System DECT Manual.
Operation
DECT operation is automatic when configured.
Conditions
1. Multiple, up to three (3) WTIMs may be linked to provide a zone with up to 24 base stations, (8
per WTIM).
2. The maximum number of WTIMs that can be installed in an iPECS system varies based on the
system model, refer to Table 1.2-1.
Programming
DECT 1. DECT Registration (PGM 491-Web only).
2. DECT Attributes (PGM 491)

2.47 IP FAX RELAY, T.38 SUPPORT
Because of there nature, Fax tones do not transmit well through IP networks, particularly when
compression is employed. To address this, the SLTM, LGCM, BRI and PRI gateways support T.38
protocol that defines the translation of fax tones to digital signals. When Fax tone is detected on a
port of an iPECS module, the module will activate a T.38 Fax relay channel to the appropriate Line
and SLT module.
Operation
Operation of this feature is automatic.
