Connecting the monitor server to the network

This topic describes how to connect the NA SS7 Monitor Software depending on the installed TX board:

Using TX 4000 boards

If the monitor server has an installed TX 4000 board, ensure that DIP switch S3 on the TX board is set to enable monitor mode. For information on setting the DIP switch, refer to the Dialogic® TX 4000 PCI SS7 Network Interface Board Installation Manual.

Connect the server to the SS7 network by attaching the cables to the 8-pin modular jacks on the TX 4000 end bracket. To connect the monitor server in this installation, use two separate cables: one cable for the transmit side of the B node connector and one cable for the receive side. Both cables use only pins 1 and 2.

Note: The protected monitoring connection point must not distort the signal more than 20 dB. This protection must be provided externally. If the loss is higher than 20 dB, the TX 4000 board may not recognize the signal. The 8-pin modular jack must receive a signal that has less than 20 dB of loss. This value includes the values from all cables and the protection circuitry.

The following illustration shows how to connect the monitor server with an installed TX 4000 board to the SS7 network and monitor SS7 traffic:

Using TX 4000C boards

If the monitor server has an installed TX 4000C board with an associated rear I/O transition board, ensure that the shunts are removed from the jumpers on the rear I/O transition board to enable monitor mode. For information on removing the shunts, refer to the Dialogic® TX 4000C CompactPCI SS7 Network Interface Board Installation Manual.

To connect the server to the SS7 network, attach a 50-pin Telco cable first to the RJ-48T trunk connector on the rear I/O transition board and then to a punchdown block. (If connecting to an E1 75 ohm trunk, connect the punchdown block to a 20-port balun.) Use two separate RJ-45 straight through cables from port 1 and port 2 on the punchdown block to connect to the network: one cable for the transmit side of the B node connector (port 2) and one cable for the receive side of the B node connector (port 1). For more information on establishing network connections, refer to the Dialogic® TX 4000C CompactPCI SS7 Network Interface Board Installation Manual.

Note: The protected monitoring connection point must not distort the signal more than 20 dB. This protection must be provided externally. If the loss is higher than 20 dB, the TX 4000C board may not recognize the signal. The RJ-48T connector must receive a signal that has less than 20 dB of loss. This value includes the values from all cables, the punchdown block, and the protection circuitry.

Using TX 5000E boards

There is no DIP switch to set for monitor mode on a TX 5000E board. Specify the monitoring function during configuration. For more information, refer to Configuring TDM.

Connect the server to the SS7 network by attaching the cables to the 8-pin modular jacks on the TX 5000E end bracket. To connect the monitor server in this installation, use two separate cables: one cable for the transmit side of the B node connector and one cable for the receive side. Both cables use only pins 1 and 2.

Note: The protected monitoring connection point must not distort the signal more than 20 dB. This protection must be provided externally. If the loss is higher than 20 dB, the TX 5000E board may not recognize the signal. The 8-pin modular jack must receive a signal that has less than 20 dB of loss. This value includes the values from all cables and the protection circuitry.
