Ip Media Module - Mitel 470 System Manual

IP media module

IP media modules can be used for systems with high call switching requirements in the
IP network. Depending on the module type a different number of VoIP and FoIP chan-
nels is available, provided by the IP media modules as required (see Tab. 24).
Note
The use of the IP media switch does not depend on the mode of operation of the standard
media switch and the configuration of the DSP chips that are used by the standard media
switch.
Fig. 13 Design of the IP media modules
IP media modules can be fitted both on the processor card CPU1 (see Fig. 9) and on
the 1PRI and 2PRI trunk cards (see Fig. 15). The modules are not stackable.
