Subboards
The following subboards (some of which are optional) can be used depending on the applica-
tion:
● CMS clock module small
– supports all 4, 8 and 12 channel CMI connections using the SLC16 board of the HiPath
3750, HiPath 3550 and HiPath 3700 systems.
– provides the master clock for digital networking.
Section 2.11 contains additional information on when CMS is used.
● MMC multimedia card
This plug-in memory card contains the CDB backup and the version-specific APS. Please
note that the MMC may only be replaced by a multimedia card approved by Siemens AG.
Cards that have not been approved may have a different internal structure which can affect
temporal access and certain features (for example, CDB backup and APS transfer).
● IMODN Integrated Modem Card New
This plug-in card allows remote service (analog mode up to 33.6 Kbps), without having to
use an external modem.
● LIM LAN interface module
This subboard makes available an Ethernet (10BaseT/10 Mbps) LAN connection using an
8-pin RJ45 jack (see Section 2.3.4.3).
● MPPI (music on hold)
