Example 1 Setting Trunk Conditioning
The trunk conditioning process (see also, T1 Trunk Conditioning Service on
page 10-5) sets known values in the signaling bits and the data bits for out-
going DS0s which are cross-connected to a T1 port experiencing alarms. The
trunk conditioning process consists of a 2.5-second transmission (indicating
call termination), followed by a continuous transmission (signaling the final
condition as chosen by the user).
Use the trunk conditioning menu items T1 F

(to set the state ofthe data
bits) for this process. You can set trunk conditioning for each end of each T1-
to-T1 connection in a dedicated map. To simplify this procedure, use the
copy command (press C). Connections to the Network and connections to
User equipment (PBX) contain different signaling bit states.
For this example, assume voice traffic is received on T1-A, and T1-B is
groomed onto T1-C to the PBX (see Figure 10-3). If T1-A fails, the DS0s which
were cross-connected to T1-C will receive trunk conditioning.

Example 2 Creating A Dedicated Map
Any ATLAS 550 port supporting dedicated bandwidth can be mapped to
any other port supporting dedicated bandwidth. A dedicated map defines
connections for dedicated bandwidth between ports and also grooms and
cross-connects bandwidth between T1 ports. For this example, the central
ATLAS 550 is equipped as shown in Figure 10-4.
Figure 10-4. ATLAS 550 with Modules Installed for Example 2
Example 2 (see Figure 10-5) contains three T1s (T1-A, T1-B, T1-C) that sup-
port dedicated bandwidth from three remote sites. Each remote T1 includes
DS0s forvoice (1-8) and data (9-24). At the central site (the ATLAS 550), each
