Model 3196RC iDSL T-DAC overview
The Model 3196RC (see figure 2) provides 16 iDSL 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 iDSL ports. The T-DAC com- bines 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 indicators, an RS- 232 configuration port and a 10/100 Ethernet management port. The rear blade contains the iDSL modem connections and WAN port connections. The 16 iDSL subscriber ports connect to compatible customer premise equipment modems for data rates up to 144 kbps over a single pair. The WAN links accept channel- ized T1 or E1 network connections.
Each iDSL 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 3196RC connects 16 iDSL remote NTUs or modems at data-rates up to 144 kbps to digital (ATM/FR/DDN/IP) networks, thus permitting multi-service access to CLECs, ISPs, and PTTs.
