The G703E1U stand-alone DSU/CSU is a compact, digital

access unit for Unframed E1 service termination. The G703E1U

data channel supports 2.048Mbps, for a line attenuation of up to

43 dB on twisted pair or coax cable. This provides an approximate

operating range up to 2km (using 22AWG). The G703E1U top

panel sports status LEDs for monitoring both the CSU and DSU

condition and slide switches for initiating digital or analog

loopback.
