t38FxLCO

Module: CISCO-WAN-T38-FAXRELAY-MIB

OID (symbolic): CISCO-WAN-T38-FAXRELAY-MIB::t38FxLCO

OID (numeric): 1.3.6.1.4.1.351.150.19.1.1.1.1.13

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object is a configurable default value for the fx(fax option) in LCO(Local Connection Option). In the absence of the MGCP fx LCO, this default value will be used. The MGCP fx LCO will always override this object.

The meanings of these enumerated types are: 'gwAndPt': means gateway controlled fax relay is preferred over fax pass through. 'gw': means gateway controlled fax relay (using NSEs). 'ptAndGw': means fax pass through is preferred over gateway controlled fax relay. 'pt': means fax pass through. 'off': means Do not do gateway controlled T.38 fax relay.

This does not preclude upspeeding or alteration of silence suppression or echo cancellation settings for the connection.

What is t38FxLCO?

This read-write enumeration (gwAndPt, gw, ptAndGw, pt, ...) sets the gateway's default fax option under Local Connection Options, used only when the call's MGCP fx LCO doesn't specify one, since an explicit MGCP value always takes precedence. An admin sets this default to control whether the gateway prefers gateway-controlled T.38 fax relay (using NSEs) or fax pass-through when no per-call instruction is given. For example, setting t38FxLCO to gw forces every call lacking an MGCP fax LCO onto NSE-based gateway fax relay rather than pass-through.
