A media gateway is built with one or more chassis modules. Several
types of chassis are available and can be classified into two
families:
• The first family consists of Rack Modules (Rack 1 or Rack
3 modules) which are shared with the Alcatel OmniPCX Office (common
hardware: same chassis, power supplies, and interface boards)
and correspond to the small and medium chassis (1.5U and 3.5U).
It should be noted that the Rack2 shelf (2.5U) is not used (for
OmniPCX Office only).
• The second family consists of Crystal shelves, inherited
from the Alcatel OmniPCX 4400 platform. A Crystal shelf is based
on the Alcatel Crystal Technology (ACT) whose main characteristic
is a meshed backplane offering full connectivity between slots.
Crystal shelves can be hosted in:
- Voice hub (VH): four slot Crystal, extendable to eight
- Wall mounted cabinet (WM1): nine slot Crystal
- M2 cabinet: one 28 slot or two 14 slot Crystals
- M3 cabinet: two 28 slot or four 14 slot Crystals |
