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 7-3 gives an example configuration for this
application.
While in DTE Loopback, data from the host is transmitted into the net-
work.
