Configuring T1 and E1 Port Parameters for CESoPSN Bundles (CTP
Menu)
This topic describes how to configure port
parameters for T1/E1 interfaces.
Before you begin:
- Disable the bundle before you modify the bundle options.
To configure port parameters for T1/E1 interfaces
for CESoPSN bundles using the CTP Menu:
- From the Main Menu, select 1) Bundle
Operations.
- Select 3) CESoPSN.
- Select a bundle from the list.
If you select an active bundle, you are prompted to disable
the bundle before configuring it.
- Select 3) Port Config.
- Follow the onscreen instructions, and configure
the options as described in Table 1.
The options vary depending on whether the bundle is T1 or E1.
Field | Function | Your Action |
---|
Port descriptor | Specifies a description for the port. | Enter a description of up to 62 alphanumeric characters.
Do not use the following characters: |
Type | 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: |
Option (for T1) | Specifies the T1 encoding method used on this bundle. | Select one: |
Option (for E1) | For E1 interfaces, configure the termination to work
with either coax or RJ-48. | Select one: |
BuildOut | For T1 interfaces, specifies the line buildout. | Select one: - 0) ~133 ft
- 1) ~266 ft
- 2) ~399 ft
- 3) ~533 ft
- 4) ~655 ft
- 5) -7.5dB CSU
- 6) -15dB CSU
- 7) -22.5dB CSU

Clock synthesizer | The following clock synthesizer settings
are set by the software, and you cannot change them: - For T1, the clock synthesizer is set to 1544 KHz.
- For E1 the clock synthesizer is set to 2048 KHz.

Clock Config | 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 Loop 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 (Adaptive End)—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 (Adaptive End), 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.

Signal | For T1 interfaces, specifies whether or not CAS signaling
is used. | Enter one: - On—Signaling is on.
- Off—Signaling is off.
