»» To Config
Security level: 3; Read security: 5
Specifies the configuration for the
To connection. The selections that dis-
play in this field are based on the type of module selected in the TO Slot
option. You must input the following information (based on the type). The
same options for setting DS0s are available for this command as with the
FROM Config option.
»» RBS
Security level: 3; Read security: 5
(Robbed Bit Signaling) Defines whether the connection has active RBS.
Where RBS is not an option, ATLAS 800

automatically assigns the cor-
rect setting. For example, a T1-to-Nx connection is set to
Off
.
» Activate Time
Security level: 3; Read security: 5
Sets the time when the map becomes active if you have selected
Auto in the
Activate Map field (see Activate Map on page 8-2). Enter this time in
hh:mm:ss 24-hour format.
» Enbl Day
Security level: 3; Read security: 5
Specifies which days of the week the map is active.
Example 1 Setting Trunk Conditioning
The trunk conditioning process sets known values in the signaling bits and
the data bits for outgoing DS0s which are cross connected to a T1 port expe-
riencing alarms. The trunk conditioning process consists of a 2.5-second
transmission, indicating call termination, followed by a continuous trans-
mission signaling the final condition as chosen by the User.
Use the trunk conditioning menu items Fault Signaling (to set the state of
the signaling bits) and Fault Data Code (to set the state of the 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 8-2). If T1-A fails, the DS0s which
were cross-connected to T1-C will receive trunk conditioning.
On Preserves the signaling bits between the connections.
Off Ignores signaling bits.
