FXS Ports 6-3
Table 6-2summarizes the configuration settings for the FXS ports, along with the available
and factory-default option settings. The parameters and settings are also described in the
following paragraphs.
Table 6-2. Main Screen Option Settings and Defaults
Notes:
1. All four ports must be set to either u-law or a-inv.
2. When a WAN or SRV port has not been selected, the default for Signal Conversion is
n/a. Once a port has been chosen then the default is off.
STATE
The State setting determines whether the port is active or inactive. An inactive port does not
occupy a time slot on a WAN link. Set the State setting to stdby (standby) for ports that are
not to be used or that have not yet been configured. Set it to actv (active) for ports that are
ready for use.
WAN
The WAN setting identifies the WAN or OWAN link assigned to this port. When choosing the
type of wan, you must also select the desired port of the WAN or OWAN port for transmission
over the T1 or E1 link.
It is not necessary to assign all FXS ports to the same WAN or OWAN link, nor to contiguous
time slots on a WAN or OWAN link.
