# Configuring T1 and E1 Port Parameters for SAToP 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 or daughter cards for SAToP bundles using the CTP Menu:

1. From the Main Menu, select 1) Bundle Operations.
2. Select 2) SAToP.
3. Select a bundle from the list.

   If you select an active bundle, you are prompted to disable the bundle before configuring it.

4. Select 3) Port Config.
5. If you are using a T1/E1 daughter card installed on a serial interface, select 1) Type, and set the type to Optional Interface: T1/E1.
6. 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.

Table 1: SAToP Bundle T1/E1 Port Parameter Settings in the CTP Menu

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. | Select one: T1 E1
Option (for T1) | Specifies the T1 encoding method used on this bundle. | Select one: B8ZS AMI
Option (for E1) | For E1 interfaces, configure the termination to work with either coax or RJ-48. | Select one: RJ48 COAX
BuildOut | For T1 interfaces, specifies the line buildout. This option is supported only on IM-8P-T1/E1 interface modules. | 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) -22.5d BCSU
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—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—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 (Adaptive End)—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 clock from the distant PBX.
