Connector Pinouts

The cable must include an RJ48C plug at the end dedicated to the WAN adapter. It must also provide the appropriate plug or cabling system at the end dedicated to the NT1. See Connector Pinouts on page 24 and your NT1 documentation for details.

E1 Link Requirements

To interoperate successfully, the adapter and the NT1 must be configured with several common E1 settings. The adapter’s E1 parameters are in accordance with the IUT-T I 431 recommendation, as follows:

Line coding: HDB3, according to IUT-T G.703

Frame format: according to IUT-T G.704

CRC4 to Non-CRC4 operation: according to IUT-T G.706 An.BLine I/O impedance: 120 Ohm ± 5%.
