For T1 CE D4 channels connected to CE ESF channels, the system copies the
configured AB bits into the CD bit position in the D4-to-ESF direction (the system
transmits ABAB). In the CE ESF-to-CE D4 direction, the system transmits only the
configured AB bits and ignores the CD bits.
The bit pattern that the system transmits on the data path can be configured.
Table 10-7 lists the configuration options for the data path.

Procedure 10-10 Configuring, enabling, or disabling trunk
conditioning
1 Enter:
CONFIG — OBJECT — PORT — <U>
↵
— TRUNK_COND
Table 10-8 describes fields used in trunk group conditioning.
Table 10-8 Trunk conditioning fields
2 Specify the channel, channels, or channel group.
a For a single channel, enter:
<channel_id>
↵
where channel_id is a number from 1 to 24 for a T1 CE port and 1 to 31 for an E1
CE port
Function Bit pattern Softkey
The Speed Touch 591s transmits an 8-character bit
pattern that matches the requirements of a downstream
device. The bit pattern is user configurable. Configurable CUSTOM
The Speed Touch 591s transmits an 8-character bit
pattern indicating that the device is out of service at the
end of the link. 00011010 MUX_OOS
The Speed Touch 591s transmits an 8-character bit
pattern indicating a fault on the upstream device. 01111111 IDLE*
Field Description
CH The channel number
CODE1 The first signaling pattern sent out during the first 2.5 s of failure when trunk
conditioning is applied
CODE2 The signaling pattern transmitted for the remaining duration of the failure, when the
channel is configured to transmit seized fault signaling. The default is 1101.
DATA The data pattern configured for transmission while trunk conditioning is applied
