Configuring T1 and E1 Port Parameters for CTP 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 for CTP bundles 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 as described in Table 25.

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

  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 64 alphanumeric characters. Do not use the following characters: 

( ; ' " ) ]

I/F Type

Specifies the daughter card as the interface type.

Select DCARD.

T1/E1 Choice

Specifies the type of interface.

Select one:

  • T1

  • E1

Fractional

Specifies whether the card is fractional.

Select one:

  • DISABLED—Card is not fractional.

  • ENABLED—Card is fractional.

T1 Line Coding

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

Select one:

  • B8ZS

  • AMI

Framing Mode

For fractional T1, ESF is the only option supported.

With ESF framing, the frame synchronization, data link, and CRC framing bits are passed across the IP network untouched.

 

Fractional Frame Transport

For fractional T1, enable or disable fractional frame transport.

Select one:

  • Frame Transport—Framing bit is transported along with data, which results in data alignment with the frame.

  • No Frame Transport—Framing bit is not transported.

E1 Connector Type

For E1 interfaces, configure the termination to work with either coaxial or RJ-48.

Select one:

  • RJ48

  • COAX

Number of Channels

Specifies the number of fractional T1 or E1 channels to transport.

For T1, select a number from 1 through 24.

For E1, select a number from 1 through 31.

Signaling

Specifies the signaling method used for fractional E1.

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 signaling channel (channel 16).

Clock Cfg

Specifies the type of clocking for the port. The default value for Clock Cfg is CTP is Loop Timed.

Select one:

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