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


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

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.

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 12.

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

  5. Click Click to Submit Bundle AND Port Changes.

FieldFunctionYour Action

Port Description

Specifies a description for the port.

Enter a description of up to 62 alphanumeric characters. Do not use the following characters:

( ; ' " ) ]

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

E1 Connector Type

For E1 interfaces, the termination is configured to work with HDB3.


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

  • -22.5dBCSU

Frame Mode (for T1 )

Specifies the frame format to be used for T1 interfaces.

Select one:

  • ESF

  • D4


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

E1 interfaces support both CCS and CAS.

For T1 interfaces, select one:

  • On—Signaling is on.

  • Off—Signaling is off.

For E1 interfaces, select one:

  • CCS

  • CAS

Clock Cfg

Specifies the type of clocking for the port.

Select one:

  • CTP is Clock Source—The PBX either returns the clock received from the CTP or it returns a clock that is traceable to the same source as the CTP node clock reference. You typically use this configuration when you configure the CTP device with a clock reference input.

  • CTP is Looped Timed—The PBX provides the clock and the CTP returns the same clock to the PBX. You typically use this configuration when the PBX has the more accurate clock source. You can configure the far end of the circuit with adaptive clocking to recover this clock if necessary.

  • CTP is Clock Source – Adap—The PBX returns the clock received from the CTP, and the CTP uses the adaptive recovered clock. You typically use this configuration when the CTP does not have a reference input and the PBX typically requires clock from the distant PBX.

    On CTP150 devices, If you set clocking to CTP is Clock Source – Adap, the first bundle activated on the interface is assigned as the adaptive master bundle on which the transmit clock is adjusted. This bundle is also the last bundle to be deactivated on the interface.
