FRACTIONAL T3 CARRIER APPLICATION

When network providers want to provide service at rates less than full T3, T3SU 300 units can be used in pairs for deploying sub-T3 rate services.

In this application example (shown in Figure 7-3), a carrier provides fractional T3 access at 8 Mbps for internet connectivity. The data connection can be either V.35 or HSSI at either location. This network uses a HSSI port at the carrier’s internet POP (point of presence) and a high-speed V.35 connection at the customer’s router. The carrier manages both the local and remote T3SU 300s via SNMP. Table 7-3gives an example configuration for this application.

While in DTE Loopback, data from the host is transmitted into the net- work.
