The following sections describe WAN Physical Configuration screen
fields and instructions for setting them.
Active WAN Port
Displays the active WAN port. In future MicroMMAC releases, this field
will be used for port redundancy.
Default WAN Port
Displays the default WAN port used for the WAN connection. The
selections are SYNC or T1.
Sync Port Type
Displays the Sync Port electrical interface type. The selections toggle
between V.35, RS422, RS232, and NONE. This field always displays a
Sync Port Type, even if the Sync Port is not the active WAN port. To use
X.21 or RS530 select RS422 and use the proper Interface Cable available
from Cabletron. See Table 1 for Cabletron Interface Cable part numbers.
The default setting for this field is V.35.
Force CTS True
Displays the source of the Clear To Send (CTS) signal. You can toggle the
selections between YES and NO. The YES (On) setting indicates that the
CTS is internally “Forced True” (from the BRIM-WT1).
The NO (Off) setting indicates that the CTS signal is received from an
external DCE (Data Communications Equipment). The default setting is
NO.
