when an DSL link is established. Circuit 106 (CTS) is set to
status ON only when link is established and circuit 105
(RTS) is in ON state.
HANDSHAKE OFF: Circuit 106 (CTS), 107 (DSR) and 109 (RLSD) are set into
status ON when an DSL link is established. Status of circuit
108 (DTR) is detected and displayed by DTR-S alarm in
both cases.
User interface type X.21
HANDSHAKE ON: Circuit I is set to status ON when circuit C is in ON state
and the DSL link is established, OFF otherwise.
HANDSHAKE OFF: Circuit I is set to status ON when the DSL link is estab-
lished and OFF otherwise independent of circuit C.
V54LOOPS ON | OFF

8.2.8 Automatic Protection Switching (APS) Configuration
GROUP
Displays the available APS groups:
LTU_08_CM> GROUP
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
APS Groups (1+1 protection, bidirectional, non-revertive)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Group Number : 1 2
Group Name : Group_08 Group_32
Configuration Status : Enabled Disabled
Working Line : LTU_08 LTU_32
Protection Line : LTU_20 LTU_44
The number of groups is set by the card configuration (LTUMODE). The group
names are defined by the card position within the subrack (the name is
Group_xx where xx is the interface address of the first system of the group.
Note: The GROUP command is only available on the first system of a plug-in.
GROUPn ON | OFF
Enables (GROUPn ON) or disables (GROUPn OFF) the APS function of a protec-
tion group.
Protection groups can only be enabled/disabled on the Master. After power-up or
reset, the protection groups on the Slave are disabled by default, but will be
automatically enabled by the Master after link startup. If a 1+1 protection group is
enabled then the line rate of the protection line will be automatically set equal to
the line rate of the working line. The LINERATE command is not available on the
protection line.
