OWAN Ports 13-9
TS16
The TS 16 setting changes the signaling usage of slot 16 for cas (Channel Associated
Signaling), ccs (Common Channel Signaling) or nos (No Signaling). In the first two options,
time slot 16 is used to carry signaling information for all channels on the E1. If nos is selected,
then time slot 16 becomes available for user data.
EVEN BIT
Setting the Even Bit parameter for inv will cause the system to invert every even bit in every
DS0 time slot. This setting should only be used if the entire E1 stream is composed of PCM
voice, to ensure minimum-ones density.
LINE LB
The Line Loopback setting controls looping of the full E1 line back to the network. When on,
this setting allows end-to-end testing of the line.
LOCAL LB
The Loopback setting controls looping of the full E1 line back to the PCM bus. The options
are off and on. When on, this setting allows testing of local equipment. The system generates
a "Keep Alive–Type 1" pattern on the E1 line.
