mdmLineCarrierLossTime

Module: Modem-MIB

OID (symbolic): Modem-MIB::mdmLineCarrierLossTime

OID (numeric): 1.3.6.1.2.1.38.1.1.3.1.1

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: Duration in 10ths of a second the modem waits after loss of carrier before hanging up. If this value is set to `255', the modem will not hang up upon loss of carrier. This allows the modem to distinguish between a momentary lapse in line quality and a true disconnect and can be useful to tune the tolerance of the modem to lines of poor quality.

What is mdmLineCarrierLossTime?

Sets, in tenths of a second, how long the modem waits after losing carrier before hanging up, with 255 meaning it never hangs up on carrier loss; an admin raises this to tolerate brief line-quality glitches on a noisy phone line without dropping the call.

Examples
