CS1000E architecture is:
- 2 CPU Penthium 4 but no network parts connected each other with both ELAN and HSP(database synchro)
- at least 1 SigServ for IP phone registering, gatekeeper application, Personnal directory and Call log.
- at least 1 Media Gateway for Virtual Conference loops, TDS, MOH, and as many TDM board as needed. With rls 4.5, MG limit is 30. With rls 5.0 it s extended to 50 MG
With rls 4.5, a connection to pstn is needed through a CS1000T or CS1000M. Also possible through another H323 or SIP trunk interact with another manufacter. (Cisco, Asrerisk, Alcatel, ...)
With rls 5.0, the network parts that was missing in the previous rls is now integrated. Hardware has been largely modify with rls 5.0 but for CS1000E only SigServ memory expansion is required
It is now a great step to do to move to that new technology. If you wish to keep on be the king of Nortel PBXs, don t hesitate to have training courses at Nortel...
