Figure 7. PCM Ports on SS7HDP Boards
The T1/E1 ports on the SS7 Signaling Boards are Safety Extra Low Voltage (SELV), that is, the apparatus
connects to the outside network via Network Termination units (NT1). Use twisted-pair, screened cables,
grounded at both ends, to ensure the EMC and error-free performance of the product. See also
Section 4.3.3, “Telecommunications” on page 28
for information on potential usage as TNV-1 ports.
The connectors are 8-way RJ45, and are labelled L3 and L4 in
Figure 5
, or L1 to L4 in
Figure 6
and
Figure 7
.
These labels can be used together with the SS7 Signaling Board position number (see
Section 5.3, “Back
Panel” on page 33
) to give each port a unique identifier for wiring schedules and unit configuration.
The connector pinout and signal descriptions are shown in
Table 5
.

SS7 Serial Interface Ports
SS7 Signaling Boards of type SPCI2S provide two synchronous SS7 serial interface ports. Both ports are
presented in a single 26-way female high density D-type connector, and use V.11 (V.35 compatible)
electrical interface characteristics. See
Appendix A
.
The connector is labelled Aux in
Figure 8
and on the products.
Table 6
identifies the ports as A and B. This
can be used with the SS7 Signaling Board position number (see
Section 5.3, “Back Panel” on page 33
) to
give each port a unique identifier for wiring schedules and unit configuration.
