Connector for TME1 module configuration
The Connector serves to link a PC or modem to a module using a serial cable (see “TME1
Serial Cable” on page 3-117). This makes it possible to program the module using the E1 Trunk
Manager tool (for E1 CAS access) or S2M Maintenance tool (S2 access).

Warning
Do not touch the TME1 module’s administrative serial interface Connector (X803)
without first disconnecting all analog extensions and trunk Connectors. Failure to fol-
low this procedure may expose the user to dangerous voltages.
The administrative serial interface Connector (X803) as well as all other Connectors
and interconnect cables should only be serviced by trained technical personnel.
