TS
If the WAN/SRV parameter is none, the TS parameter will always be n/a. If the WAN/SRV
parameter is wan (or a WAN port) then TS setting identifies the time slot on the WAN link to
which this port is assigned. Values range from 1 to 24 for T1 links and 1 to 31 (excluding time
slot 16 in cas or ccs mode) for E1 links.
MODE
This option displays the selection of modes. In ds0dp mode, the port will provide a common
bit and byte clock to be used by the attached DTE device for both receive and transmit. When
one port is set to ds0dp all other ports will default to the DS0-DP mode as well. Similarly,
when one port is changed to one of the G.703 modes (Codirectional or Contra directional), any
port set for the DS0-DP mode will default to the Contra directional mode. The contr selection
configures the port for the Contra directional mode. In this mode, the card supplies both the
transmit and receive clocks to the DTE. The codir selection configures the port for the
Codirectional mode. In this mode, the clocks and data make up a composite signal. The clocks
must be derived from the data.
CLK
This option allows the selection of the desired clocking mode when in the DS0-DP mode.
When set to int, the card generates the bit and byte clocks to the DTE. When set to ext, the
card receives the bit and byte clocks from the attached device. All ports must have the same
clock setting, therefore, when one port is changed, all ports are changed. When a G.703 mode
is selected, this option defaults to n/a. See Table 18-2 for further detail on CLK selection.
LB
This option allows users to set local loopbacks. The off option is for no loopbacks. The dte
selection loops data towards the DTE. The net option loops data towards the network.
LB GEN
This option allows users to set local loopbacks. The off option is for no loopbacks. The other
options are ocu, dsu, csu, ds0 and force the card to send the appropriate DDS latching
loopback code towards the remote end. This option will only function in the DS0-DP mode.
