IV. Edge access layer
The edge access layer connects the subscribers and terminals with the network by
various access means. It converts the original information formats into those that can
be transferred over the network. The following devices can connect with the network:
Integrated access device
The integrated access device (IAD) is a user access layer device in the NGN. It is
used to introduce the data, audio, and video services to the packet based
network.
Access media gateway
The access media gateway (AMG) provides multi-service access, including
analog user access, integrated services digital network (ISDN), V5, and x digital
subscriber line (xDSL).
SIP phone
The SIP phone is a kind of multimedia terminal device that supports the Session
initiation protocol (SIP).
H.323 phone
The H.323 phone is a multimedia terminal device that supports the H.323
protocol.
SG
The Signaling gateway (SG) connects the No.7 signaling network with the IP
network. It converts the N0.7 signaling of the public switched telephone network
(PSTN) and the signaling of the IP network.
TMG
The Trunk media gateway (TMG) is located between the circuit switched network
and the IP packet switched network. It converts the formats between pulse code
modulation (PCM) signal streams and the IP media streams.
UMG
The Universal media gateway (UMG) converts the media stream formats and the
signaling. It can act as a TMG, a built-in SG or an AMG. It can connect the
devices such as PSTN exchange, private branch exchange (PBX), access
network, network access server (NAS), and base station controller.

1.3 System Features

The MRS6100 provide the following features:
I. Open protocols and standard NMS interfaces
The MRS6100 supports open protocols like the SIP and the media gateway control
protocol (MGCP). It provides various interfaces to connect with the entities, such as
softswitch devices, AS, media gateways, IP intelligent terminals, and NM center. With
these interfaces, the MRS6100 can meet your special networking requirements.
