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).

The administrative serial interface Connector (X803) as well as all other Connectors
and interconnect cables should only be serviced by trained technical personnel.
