Configuring the Missing Packet Fill Pattern for CTP Bundles (CTP Menu)

This topic describes how to specify the fill pattern that the CTP device inserts when IP packets are dropped.

Before you begin:

Disable the bundle before you modify the bundle options.

To configure the missing packet fill pattern for CTP bundles 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 option 3) Missing pkt fill pattern as described in Table 1.

Table 1: CTP Bundle Missing Packet Fill Pattern Parameter Setting in the CTP Menu
Field	Function	Your Action
Missing pkt fill pattern	Specifies the data that the CTP device inserts into the circuit bit stream when an IP packet is dropped. The number of bits inserted is equal to the number of bits in the missed packet. When the bundle is down, the port sends the value of the least significant bit (LSB) of the missing fill pattern. This data insertion method prevents a loss of bit count integrity to attached circuit devices and encryptors.	Enter two hexadecimal digits. You must enter a value other than ff. This field does not require the 0x characters.
