Modifying, Enabling, and Disabling a Port

To modify a Port:

Click the expand () Icon next to the entry you wish to modify.

Port Table View Entry

 

T1 Ports - Field Definitions

Identification/Status - Field Definitions

The Identification/Status Panel controls the network identity of the port and its administrative state (Up or Down). It also provides the port's current service status and when that status last changed.

Port Alias

Specifies an alias for the port. This text is configured by the operator for exclusive use by SNMP-based element and network management systems to assign a key to the port or interface, that is unique across the managed network. Examples would be "Node10Port5" and "VerizonPort5".

Description

Specifies a description for the port. Maximum entry: 128 characters.

Admin State

Specifies the administrative state of the port.

  • Enable: Enables the port.
  • Disable: Disables the port.

Lookback Type

Specifies the loop back status of the port.

Loopback is used when testing the line so that any potential fault can be isolated to a particular section of the line. The various loop types control the point at which the loop happens and helps narrow down the faulty section of the line. The Line type is the only loopback type available for E1.

Loopback disrupts normal traffic on the line. Consequently, the loopback type option should be set to None when not actively performing troubleshooting activities related to the associated port.

Physical/Date Layer

Used to specify the Layer 1 and Layer two properties of the port.

Signaling Type

Specifies the signaling type for the port. ISDN or CAS.

DS1 Framing

Specifies the framing type used on a T1 Port. The Choices available for T1 are ESF and D4. DS1 Framing options must match at each end of the line.

D4 or Super Frame (SF)
A Super Frame consists of twelve consecutive 193-bit frames of data.

ESF or Extended Super Frame
An Extended Super Frame consists of twenty-four consecutive 193-bit frames of data.

Compatibility
Due to the unique bit sequences exchanged, the framing schemes are not compatible with each other. These two types of framing (SF and ESF) use their 8 kbit/s framing channel in different ways.

Line Coding

Specifies the line coding for the port.
In telecommunication, a line code (also called digital baseband modulation or digital baseband transmission method) is a code chosen for use within a communications system for baseband transmission purposes. Line coding is often used for digital data transport.

Line coding consists of representing the digital signal to be transported by an amplitude and time-discrete signal that is optimally tuned for the specific properties of the physical channel (and of the receiving equipment). The waveform pattern of voltage or current used to represent the 1s and 0s of a digital data on a transmission link is called line encoding. The common types of line encoding are unipolar, polar, bipolar, and Manchester encoding.

Trunk Type

Specifies the trunk type for T1 Ports. Valid entry: Short Haul or Long Haul

Cable Length

Specifies a range of length (in feet) for Short Haul trunk types.

Line Buildout

Specifies the attenuation used for a Long Haul type T1 port (in decibels).

Enabling and Disabling Logical Interfaces

To enable a Logical Interface:

  1. Select the check box next to the entry you wish to enable.
  2. Click the Enable () icon at the top of the table. 

To disable a Logical Interface:

 

  1. Select the check box next to the entry you wish to disable.
  2. Click the Disable () icon at the top of the table.
