Figure 13-1. G.703 T1/E1, T2/E2 Interface Module (AS/11579 shown)
The G.703 T1/E1, T2/E2 Interface Module (Figure 13-1) provides physical and electrical
connection between the external terrestrial device and the internal circuitry of the SLM-5650A’s
modulator and demodulator. By convention, a modem is Data Communications Equipment
(DCE), where Tx data enters the data interface and Rx data exits it.
The G.703 T1/E1, T2/E2 Interface Module supports balanced or unbalanced, and differential/
single-ended operation. The plug-in interface has full duplex capability.
