Configuring T1 and E1 Port Parameters for VComp 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 VComp bundles using the CTP Menu:
- From the Main Menu, select 1) Bundle
Operations.
- Select 4) VCOMP.
- If you are creating 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.
Do you want to configure this card for all VCOMP? y[n]:
- 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.
- If you are configuring an existing bundle,
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: |
LineCoding | Specifies the T1 encoding method used on this bundle. | 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
|
Frame 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.
|
Signal (for T1) | For T1 interfaces, specifies whether or not CAS signaling
is used. | Enter one: - On—Signaling is on. Signaling lead input on each
channel is transported end-to-end.
- Off—Signaling is off.
|
Signal (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).
