SS7TE2 and SS7TE3 Pinouts and
Cable Requirements
This appendix shows the pinouts for the SS7TE2 and SS7TE3 PIC cables and
provides the cable requirements.
The SS7TE2 uses CAT 5, 26AWG minimum cables. The daisy-chain crossover cables
are two feet long and must have ferrite beads clipped on to both ends. In addition, a
ferrite bead must be clipped onto the cable that connects to the customer termination
equipment.
The SS7TE3 uses CAT 5 26AWG minimum cables.
A ferrite bead must be installed on all SS7TE2 cables so that the system remains in
compliance with regulatory limits on electromagnetic interference (EMI) for Class A
devices.
To install a ferrite bead on a cable, refer to Figure B-1 and follow the steps below.
Follow the same procedures for the two-foot crossover cables used to daisy-chain the
SS7TE2 PICs together but install two ferrite beads: one on each end. (To view part
numbers, from the home page of NTL, select
