Introduction
The Clock Module Small CMS (S30807-Q6928-X) is an optional subboard for the HiPath 3000
central control boards and guarantees greater clock accuracy.
Recommendations for CMA and CMS utilization
Table 3-21 provides recommendations for the implementation of CMA and CMS subboards
based on
● the type of network (ISDN S
0
, ISDN S
2M
or Ethernet/IP (10/100 BaseT))
● the trunk connection available (no trunk/analog trunk, ISDN S
0
or ISDN S
2M
) and conse-
quently, the possible provision of a digital reference clock

Caution
Place the central control board on a flat surface before inserting the CMS subboard.
The spacing bolts supplied guarantee the correct insertion of the subboard, so you
should always mount them (see Figure 3-6).
Otherwise you may damage the board.
