Configuring Circuit Startup Parameters for CTP Bundles (CTP Menu)

This topic describes how to configure advanced options that are related to circuit startup. Set these parameters to the same values on the local and remote CTP devices.

Before you begin:

Disable the bundle before you modify the bundle options.

To configure circuit startup parameters using the CTP Menu:

From the CTP Main Menu, select 1) Bundle Operations.
Select 1) CTP.
Select a bundle from the list.
If you select an active bundle, you are prompted to disable the bundle before configuring it.
Select 2) Config.
Select 10) Advanced Options.
Configure options 4, 5, 6, 7, 8, and 15 as described in Table 1.

Table 1: CTP Bundle Advanced Options Parameter Settings for Circuit Startup in the CTP Menu
Field	Function	Your Action
Consecutive pkts loss to starve	Specifies how many consecutive circuit packets the IP network must drop before the CTP device restarts the circuit. We recommend that you set the parameter to a larger value when the IP network uses packet-encrypting devices. These devices cause momentary interruption in packet flows when encryption keys are updated.	Enter a number from 1 through 64.
In sequence pkts after starve	Specifies the number of in-sequence packets the CTP device must receive after a starvation before the circuit transitions from in-sync to running.	Enter a number from 1 through 64.
OAM Chan Rate (pkt/sec)	Specifies the number of OAM packets per second that the circuit sends to the remote CTP device.	Enter a number from 1 through 255.
OAM pkts for Sync	Specifies the number of OAM packets that the circuit must receive before the state moves from no synchronization to in synchronization.	Enter a number from 1 through 255.
OAM pkts for Sync Loss	Specifies the number of received OAM packets that the CTP device misses before the state of the circuit moves from in synchronization to no synchronization.	Enter a number from 1 through 255.
OAM-free CTP bundle	Specifies whether to use the full duplex OAM communication to bring CTP bundle to the running state.	Select one: No—CTP bundle uses the full duplex OAM communication to bring CTP bundle to the running state. When a bundle is activated, the CTP device sends OAM packets to the remote circuit until the required number of packets is received. The circuit then changes its state to ’running’ and begins sending data packets. Yes—CTP bundle does not use the full duplex OAM communication to bring CTP bundle to the running state. When a bundle is activated, the circuit directly changes its state to ’running’ and begins sending data packets. When set to ’Yes’, other bundle OAM parameter values are ignored.
