4. 5. 3 Equipping the call manager card CPU1
The Call Manager card is part of any communications server and is required for a
fully functional system. It is already fitted ex-works and only needs to be removed
in the event of repairs (see "Operation and Maintenance", from page 210) or when
expanding the system with modules. The Call Manager card only fits into slot 1 (see
Fig. 25).
4. 5. 4 Fitting system modules
With system modules a distinction is made between modules expandable as an op-
tion (DSP modules, IP media modules, Call charge modules) and mandatory mod-
ules (RAM module). The system cards (Flash card, EIM card) are always required.
This chapter only describes the procedure for fitting system modules that are ex-
pandable as an option (DSP module, IP Media module, call charges module). The
RAM module only need to be replaced in the event of repairs or maintenance work
(see "Operation and Maintenance", from page 210).
