Release 5.1 Supplement for Remote Annexes
MMP Groups
An MMP group is a set of one or more Remote Annexes that act as a
single entity for any MP links that terminate on any of the Remote
Annexes in the group. MMP groups usually are organized to correspond
to telco hunt groups. All Remote Annexes in an MMP group must reside
on the same Ethernet segment and, where applicable, on the same IP
subnet. A Remote Annex can belong to a single MMP group only.
Otherwise, Remote Annexes can be grouped any way, with multiple
groups allowed on the same Ethernet segment.
MMP groups are identified by their end point discriminator, which
comprises the port parameters mp_endpoint_class and
mp_endpoint_address. All the Remote Annexes in an MMP group must
have the same mp_endpoint_class and the same
mp_endpoint_address. When MMP is enabled and mp_endpoint_class
is set to loc or psndn, the mp_endpoint_address parameter indicates an
endpoint discriminator address, which is the number of the hunt group
or the name of the rotary served by the MMP group. Refer to the Remote
Access Concentrator Software Reference for complete descriptions of
these parameters.
Establishing MMP Connections
When a remote user dials the number for a hunt group, a Remote Annex
belonging to the MMP group assigned to that hunt group answers the
call. The remote user can use any type of line: BRI, PRI, or asynchronous.
The answering Remote Annex detects the type of call automatically and
answers it appropriately, creating an MP link.
