The ATLAS Frame Relay/Router option allows the ATLAS series of Inte-
grated Access Devices to act as a voice/data frame relay access device
(FRAD), a private network frame relay switch, a frame relay concentrator,
and an internal IP router. In addition, the ATLAS Frame Relay/Router op-
tion manages currently available bandwidth and switching applications.
The Frame Relay/Router option provides the following functions:
•
Routes Internet Protocol (IP) traffic between a public or private frame re-
lay network and the integral 10BaseT Ethernet port.
•
Concentrates IP traffic from a public or private frame relay network to
one or more serial ports (V.35). The protocol passed over the serial port
is frame relay.
•
Passes Systems Network Architecture (SNA), Bisync, and other legacy
protocols between a public or private frame relay network and an exter-
nal DTE running frame relay to ATLAS. (May require the HDLC Mod-
ule—P/N 1200222L1.)
•
Performs voice compression/decompression (G.723.1) and interfaces to
either a Private Branch Exchange (PBX) or the Public Switched Tele-
phone Network (PSTN). (This feature requires an additional option
module, the VCOM Module—P/N 1200221L1.)
Table 1-1 lists the specifications for the frame relay features.
