Model 3096RC G.SHDSL T-DAC overview
The Model 3096RC (see
figure 2
) provides 16 G.SHDSL subscriber ports and 4, 8, 12, or 16 T1/E1 WAN
uplink ports. A built-in digital cross-connect switch provides completely flexible grooming: the capability to
connect any DS0-channel to any other DS0-channel from the WAN uplink ports or the G.SHDSL ports. The
T-DAC combines a time-slot multiplexer and a centralized web-based management system on a front and rear
blade for insertion in a rack with a CPCI mid-plane architecture. The front blade contains LED status indica-
tors, an RS-232 configuration port and a 10/100 Ethernet management port. The rear blade contains the
G.SHDSL modem connections and WAN port connections. The 16 G.SHDSL subscriber ports connect to
compatible customer premise equipment modems for data rates up to 4.6 Mbps service over a single pair. The
WAN links accept channelized T1 or E1 network connections.
Each G.SHDSL port requires only a single twisted pair (2-wires) for full-duplex data transmission at ranges in
excess of 9 km (24 AWG). TC-PAM line encoding ensures spectral compatibility within existing voice/data
bundles. Each WAN port terminates T1/E1 with flexible any-to-any DS0 mapping. The entire system can be
managed in-band (via T1/E1 Frame Relay/PPP links) or out-of-band from a web browser by means of
SNMP/HTTP-based management screens.
The Model 3096RC connects 16 G.SHDSL remote NTUs or modems at data-rates up to 4.6 Mbps to digital
(ATM/FR/DDN/IP) networks, thus permitting multi-service access to CLECs, ISPs, and PTTs.
