as the Signaling Server and the Media Cards installed in the Media Gateway, require both ELAN subnet and TLAN subnet connections.

An MG 1000T provides CS 1000E system access to:

•PSTN

•Nortel Integrated DECT (DECT)

•Nortel WLAN IP Telephony

The MG 1000T have sufficient intelligence to handle digit manipulation and call routing functions without using the resources of the Core Call Server. The SSC in the MG 1000T Core functions as the Primary Controller for the MG 1000T. This MG 1000T Core with its MG 1000T Expander provides 8 slots for IPE cards. The additional four Survivable MG 1000T Expansions with their Media Gateway Expanders provide an additional 32 IPE slots. They are linked to the MG 1000T Core. This maximum configuration allows up to 20 E1 interfaces or 40 IPE card slots.

The MG 1000T Expander cannot support PRI/D-Channel type cards. The MG 1000T Expander are typically used for Media Cards or IPE cards that do not require Clock Controller support. Voice and signaling connections between an MG 1000T and a CS 1000E use MCDN and IP Peer Networking through their associated Signaling Server. The network used to transport these connections can be engineered so that the gateways can be located anywhere in a QoS-managed IP network following the engineering guidelines for IP Peer Networking. For additional information, refer to

IP Peer Networking: Installation and Configuration (553-3001-213).

A Signaling Server provides the software used to provide IP Peer Networking features between the MG 1000T and the network. The number of Signaling Servers required will depend upon the capacity and level of redundancy required. For additional information, refer to Signaling Server: Installation and Configuration (553-3001-212).

Figure 37 on page 155 is an example of an IP Phone call through an MG 1000T to the PSTN.
