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).
