Module: Nortel-Magellan-Passport-GsmIwfMIB
OID (symbolic): Nortel-Magellan-Passport-GsmIwfMIB::gsmCsRlpT1AckTimer
OID (numeric): 1.3.6.1.4.1.562.2.4.1.127.3.10.1.4

Type: Unsigned32
Access: read-write
Description: This attribute specifies the time in milliseconds within which an acknowledgment of a sent frame must be received. Once this timer expires, the transmitting Radio Link Protocol (RLP) entity shall assume that the frame was lost. During the Exchange Information (XID) negotiation, both RLP entities (mobile station and IWF) can agree to use specific value for this timer (T1). The IWF attempts to negotiate to the value specified by this attribute. The default value for t1AckTimer is 520 msec for the full14k5Rate instance of this component, 480 msec for full12kRate, 540 msec for full6kRate, and 780 msec for half6kRate. The negotiated value can be viewed in the component GsmIwfRlpOp attribute t1AckTimer. Changes to this attribute do not effect existing calls.
What is gsmCsRlpT1AckTimer?
Sets the RLP T1 acknowledgment timer (380-1020 ms) this GsmIwfCallServer proposes during XID negotiation; once it expires without an ack, the transmitting RLP side assumes the frame was lost and retransmits, so lowering it too far on a high-latency radio path risks unnecessary retransmissions.
