Prosody X PCI Express R1 Card – Installation Guide
The identification of the input and output of the network termination point is the
responsibility of installation personnel.
120 ohm line interface
Each E1 interface on the card carries one 30-channel service connection via a
screened twisted pair cable of 120 ohm characteristic impedance. There is one
transmit pair and one receive pair.
120 ohm trunk connection
The 8-contact RJ45 modular plug on the cable between the adapter and the network
must be wired as follows:
Pin

Function
Direction
4 LTT Transmit
(tip) output
5 LTR

(ring)
output
1 LRT Receive
(tip) input
2 LRR

The cable and plug must be shielded types to ensure EMC compliance.
If a cable is to be produced to wire into a network trunk connection, the connector on
the network end of the cable must be wired as appropriate for the network terminating
unit provided.
