Configuring T1 and E1 Port Parameters for VComp Bundles (CTPView)

This topic describes how to configure port parameters for T1/E1 interfaces.

If you create a new VComp bundle on a T1/E1 interface module and there are no other bundles configured on the interface, you are prompted to specify whether the T1/E1 interface is dedicated to VComp bundles.

  • If you specify yes, all ports on the interface can be used for VComp bundles, and you cannot configure any other bundle types on the interface.

  • If you specify no, you can configure other types of bundles on the interface. However, you cannot use port 2 for VComp bundles.

Before you begin:

  • Log in to the CTPView software at least at the Net_Admin level.

  • Connect the CTPView server to the CTP device for which you want to configure bundles.

  • Disable the bundle before you modify the bundle options.

To configure T1 and E1 port parameters using CTPView:

  1. In the side pane, select Bundle > Configuration.
  2. Run your mouse over the Display and Select an Existing Bundle bar.
  3. In the table of bundles, select the bundle that you want to modify.
  4. Under Port Options, configure the parameters described in Table 1.

    The options vary depending on whether the bundle is T1 or E1.

  5. Click Click to Submit Bundle AND Port Changes.

Field Function Your Action

T1/E1 Choice

Specifies the type of interface.

The type of interface that you select affects the default packet size and buffer sizes for the bundle.

Select one:

  • T1

  • E1

T1 Line Coding

For T1 interfaces, specifies the T1 encoding method used on this bundle.

Select one:

  • B8ZS

  • AMI

Framing Mode

For T1 interfaces, specifies the framing method.

Select one:

  • ESF—Extended Superframe (ESF) Framing. Frame synchronization, data link, and CRC framing bits are passed across the IP network untouched.

  • D4—Superframe Framing.

Line Buildout

For T1 interfaces, specifies the line buildout.

Select one:

  • ~133 ft

  • ~266 ft

  • ~399 ft

  • ~533 ft

  • ~655 ft

  • -7.5dB CSU

  • -15dB CSU

  • -22.5dB CSU

Signaling (for T1)

For T1 interfaces, specifies whether or not CAS signaling is used.

Select one:

  • On—Signaling is on. Signaling lead input on each channel is transported end-to-end.

  • Off—Signaling is off.

Signaling (for E1)

For E1 interfaces, specifies the signaling method used.

Select one:

  • CSS—Common channel signaling. The common channel carries data messages that convey signaling for the circuits between two devices.

  • CAS—Channel associated signaling. Each traffic channel has a dedicated signalling channel (channel 16).
