This recommendation supports the 3GPP2 All-IP Step 1 Evolution
Path by providing Stage-1, 2 and 3 for the architecture identified
in Figure 3.1, "Legacy MS Domain Support for Circuit Mode IP
Transport Call Delivery".

The Legacy MS Domain provides support for existing MSs (e.g.,
analog, IS-95-A, IS-95-B, IS-2000) in an IP core network
environment. The Legacy MS Domain supports the features and
capabilities provided in a legacy network in a manner transparent
to the user. New features and capabilities supported by the IP core
network may be made available to subscribers where they are
supported by MS capabilities.

This document specifies signaling reference point zz
(MSCe-to-MSCe). This reference point supports Media
Gateway-to-Media Gateway bearer streams (i.e., yy reference point).
The yy reference point is used as a bearer facility for legacy
voice calls and is specified in [3GPP2-4].
