ABSTRACT:
In situations where 2.048 megabit E1 (32 channels) access to the customer premise is not available, the only option other than provisioning a 45 megabit T3 line to the customer premise is to provision two 1.544 megabit T1 (24 channels) lines, and inverse multiplex the customer's E1 signal onto the two T1 lines at the customer premises. At the network point-of-presence (POP), the applicable thirty-two channels of the two T1 lines are remultiplexed onto a single E1 line. The remaining sixteen channels of the two T1s are wasted. To prevent wasting these channels, the present invention provides an additional standard customer interface to enable transport of multiple 64 kilobit applications. The resulting N.times.64 kbit data stream can then be multiplexed onto the two T1 lines transporting the E1 signal. The inverse multiplexer at the network point-of-presence (POP), while remultiplexing the 32 T1 channels onto an E1 line, also extracts the DSOs carrying the N.times.64 kbit customer payload and provides these DSOs a G.703 compliant network interface for multiplexing onto T1 or T3 lines for transport over the network.
