Configuring a DS3-ATM Trunk Module
Connecting a DS3-ATM trunk module
Connecting a DS3-ATM trunk module
Connect the DS3 line to the RX LN and TX LN connectors on a DS3-ATM trunk
module, using two 75-ohm coaxial cables (RG 59/U).
To configure a DS3-ATM connection, connect the receive and transmit cables to the
trunk module as shown in Figure 11-1.
Figure 11-1. Connecting a DS3-ATM trunk module for the Stinger MRT 23
Note
Connection to the DS3-ATM trunk module for the Stinger MRT 19 is
performed in an identical way. However, the locations of PORT 1 and PORT 2 are
reversed.
Inform your service provider that the equipment is connected, so the provider can
activate the line.
Interpreting DS3-ATM status lights
Several status lights on the front panel of the DS3-ATM trunk module indicate the
status of the module and its ports. Figure 11-2 shows the front panel and status lights
of the DS3-ATM trunk module.
Note
The DS3-ATM module depicted in Figure 11-2 is for an MRT 23. The status
lights are positioned differently on an DS3-ATM module for the MRT 19, but indicate
the same conditions on both modules.
