TSC Connectors and Cables

This section describes the connectors and cables required to connect a Telecom Signaling Card to the signaling network. A TSC is connected to the signaling network from a connector on the end-plate of its PCI adapter card.

The connectors and cables required depend on the type of TSC (and, in the case of an E1/T1 card, the telecommunications protocol to be used). Four sets of connectors are described here:

Connection	Description	Section Reference
E1	To connect an E1/T1 TSC to the network using the E1 protocol.	“E1 Connections”
T1	To connect an E1/T1 TSC to the network using the T1 protocol.	“T1 Connections”
V.35	To connect a V.35 TSC to the network.	“V.35 Connections”
Loopback	To connect up a TSC for loopback testing.	“Loopback Hoods”

In addition, the optional connection panels that can be used to organize TSC cabling are described in “Connection Panels”.

E1 Connections

This section describes the connections required to connect an E1/T1 TSC to the signaling network, when the E1 protocol is to be used.

The E1 cable assembly connects to the E1/T1 TSC by means of a 36-pin male connector, shown in Figure B-3 “TSC 36 Pin Connector (E1/T1)”.

Figure B-3 TSC 36 Pin Connector (E1/T1)

The cable assembly provides four ports to the network. These ports may interface to the network using either four RJ-45 connectors or eight BNC connectors (grounded or ungrounded). The RJ-45 and BNC connector types are illustrated in the figures below.

T1 Connections

This section describes the connections required to connect an E1/T1 TSC to the signaling network, when the T1 protocol is to be used.

The T1 cable assembly connects to the E1/T1 TSC by means of a 36-pin male connector, shown in Figure B-3 “TSC 36 Pin Connector (E1/T1)”.

The cable assembly then provides four ports that interface to the network using four RJ-45 connectors. The RJ-45 connector type is illustrated in Figure B-4 “RJ-45 Connector (E1/T1)”.

T1 Connector Pinouts

The pinouts for the T1 cable assembly are provided in the table below. The table lists the pins of the port connector and for each port gives the corresponding pins on the 36-pin TSC connector.

V.35 Connections

This section describes the connections required to connect a V.35 TSC to the signaling network.

The V.35 cable assembly connects to the V.35 TSC by means of a 120-pin male D-shell connector, shown in Figure B-6 “TSC Connector (V.35)” below.

Figure B-6 TSC Connector (V.35)

There are two types of V.35 cable assembly that can be used. One provides a DTE protocol connection and the other provides a DCE protocol connection.

A V.35 cable assembly provides four ports to the network. These ports interface to the network using four 34-pin female DCE connectors or four 34-pin male DTE connectors. These are illustrated below in Figure B-7 “V.35 DTE Connector” and Figure B-8 “V.35 DCE Connector” respectively.

Loopback Hoods

Loopback hoods are used in the hardware validation procedure to connect the output of a TSC network port to the input of the same TSC network port. This allows a TSC to be operated and tested without direct connection to the network. There are two general types of loopback hood:

Cable Loopback Hoods: These connect to the end of the TSC cables (to the network end) and can therefore be used to test the operation of the TSC in conjunction with the TSC network cables. These hoods are available in three types, for the different types of cable, and are supplied with the cables:
Loopback Hood Type
HP Part Number
E1/T1 RJ-45
5063-1340
V.35 DTE
5063-1334
V.35 DCE
5063-1335
Note that Cable Loopback Hoods are not supplied for E1/T1 BNC cables, since loopback is easily accomplished with these cables.
Card Loopback Hoods: These connect directly to the TSC (to the TSC end-plate connector on the rear panel of the TSU) and can therefore be used to test the operation of the TSC in isolation from the TSC network cables. These hoods are available in two types, for the different types of card, and are supplied with the cards:
Loopback Hood Type
HP Part Number
E1/T1
5063-1346
V.35
5063-1336

Connection Panels

To aid installation and maintenance, all cabling between a TSC and the signaling network can be routed via an optional connection panel in the server cabinet in which the TSCs are located (the TSCs are housed either directly in the server or in one or more Telecom Signaling Units located in the server cabinet).

The connection panel contains a number of sockets of a certain type, each corresponding to one TSC port. The TSC cables connect to the sockets of the panel from where they are connected to the network.

Connection panels are available from HP for the different types of cable assembly. These are listed in the table below which details the number of TSC ports supported, along with the HP product number and part number.

Table B-15 Connection Panels

Connector Type	Number of Ports	Connection Panel HP Product Number	Connection Panel HP Part Number
RJ-45 Grounded	12	J3844A	J3844-80100
BNC Grounded	12	J3845A	J3845-80100

A BNC connection panel is illustrated in Figure B-9 “BNC Connection Panel (Example for E1) ”. The RJ-45 connection panel is similar but with one hole per port.
