Installing a Stinger MRT
Connecting cables to a Stinger MRT unit
Although the STS interfaces are permanently installed in the MRT chassis, the TAOS
software addresses them as slot 17 to maintain command-line-interface consistency
with other Stinger models.
Connecting the trunk module
The trunk module cables are either coaxial (for DS3), shielded dual pair with RJ-48
connectors (for T1 or E1), or fiber optic (for OC-3/STM-1 optical).
For additional details about configuring the trunk modules, see the chapter in this
guide that deals with the appropriate trunk module.
Inform your service provider that the equipment is connected, so the provider can
enable the line.
OC3/STM1-ATM trunk module connections
An OC3-ATM trunk module requires duplex SC fiber optic cable. The following
illustration shows the trunk module for the Stinger MRT 23 to illustrate this type of
connection. Physical ports on the trunk module for the Stinger MRT 19 are
positioned and labeled in reverse order, from left to right, see Figure 2-7 and Figure
2-8 on page 2-8 for details.
Caution
!
the excess cable length in a figure-eight pattern. Do not wind excess cable into
circular coils.
To connect the cables to an OC3-ATM trunk module, align the small rectangular key
on the head of the cable connector with the slot in the connector on the trunk
module and carefully insert the head of each cable into the proper connector on the
trunk module. See Figure 3-24.
Note
Clean any fiber optic cables prior to connecting them.

DS3-ATM trunk module connections
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), as shown in Figure 3-25. The
illustration shows the trunk module for the Stinger MRT 23 to illustrate this type of
connection. Physical ports on the trunk module for the Stinger MRT 19 are
positioned and labeled in reverse order, from left to right, see Figure 2-9 and Figure
2-10 on page 2-9 for details.
