Abstract
A multiple rate network interface (42) is provided to interface a telecommunication network and a digital telecommunication switch (48). The multiple rate network interface (42) may operate in at least a first mode and a second mode. The first mode allows telecommunication signals in a first format to be exchanged between a telecommunication network and the digital telecommunication switch (48). The second mode allows telecommunication signals in a second format to be exchanged between a telecommunication network and the digital telecommunication switch (48). The first format may be synchronous transport protocol level one (STS-1) and the second format may be digital signal level three (DS3). The multiple rate network interface (42) includes a first processing circuit, a second processing circuit, and a control circuit. The first processing circuit may include a bipolar interface (60), an STS-1 terminator (64), a signal switching circuitry (70), a VT 1.5 terminator (66), and a payload processor (68). The second processing circuit may include the bipolar interface (60), the signal switching circuitry (70), and an M13 multiplexer (62). The control circuit may be implemented using a microprocessor and programmable logic devices.
