variants.

1.5 Connectivity

TDM SS7 signaling can interface to the Signaling Gateway using balanced 1544 kbit/sec (T1) balanced

connections in accordance with G.733 or 2048 kbit/sec (E1) connections in accordance with G.703. SS7

signaling can also be presented on a V.11 (56/64 kbit/sec) synchronous serial interface.

MP2A signaling used for communication between paired Signaling Gateways can be received at the conveter

using 4 x 1 Gbit/sec RJ45 Ethernet interfaces.

1.6 User Interface

The Signaling Gateway provides serial port and telnet connections for configuration and management. All

ports provide identical functionality and operate using text-based MML (Man Machine Language) commands

in accordance with CCITT recommendations.

The serial and telnet ports allow you to configure the Signaling Gateway for operation and to carry out

subsequent modifications to the configuration. They allow you to read the current status of the various

signaling entities and to view the current active alarms and a history of past alarm events.

The Signaling Gateway provides two levels of SNMP support:

• Basic V1 SNMP functionality which uses the DK4032 MIB and reports counts of current alarms to an

SNMP manager.

• Enhanced SNMP functionality which offers SNMP V1, V2c and V3 SNMP. Enhanced SNMP supports SNMP

traps and event reporting using the DSMI MIB.

See Chapter 10, “Signaling Server SNMP” for more information.

The Signaling Gateway has alarm indicators on the front panel and alarm relays for connection to an

integrated management system.

1.7 Configuration and Program Storage

All configuration data is stored on hard disk and is automatically recovered after system restart.

Configuration data may optionally be backed up to a remote computer, previously backed-up configurations

can be reloaded.

The SS7G31 and SS7G32 products include two hard disks configured in a RAID array. Refer to Section 7.7,

“Hard Disk Management” on page 146 for details.

All operating software is stored on hard disk and is automatically initiated after system restart. The operating

software can be updated either by reading a new software release from FTP, USB device or CDROM. In both

cases, software update is initiated by MML command. See Section 4.11, “Updating System Software” on

page 31 for details. Following a software update, the Signaling Gateway automatically uses the saved

configuration data so that there is no need to reenter the configuration parameters.
