Introduction
The CBCC (Central Board with Coldfire Com) board performs all central control and switching
functions for HiPath 3550.
Subboards
The following subboards (some of which are optional) can be used depending on the applica-
tion:
● CMS clock module small
– supports all two-channel cordless connections to the HiPath 3550, HiPath 3350, Hi-
Path 3500 and HiPath 3300 systems.
– 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.
● ADPCM (CMA) clock module
– supports the 4-channel CMI connection over BS3/1 to the HiPath 3550, HiPath 3350,
HiPath 3500 and HiPath 3300 systems.
– in the same way as the CMS clock module small, provides the master clock for digital
networking.
Section 2.11 contains additional information on when CMA 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 2.4.3.3).
