A- CLLI

The CLLI code that identifies the "A" termination of the facility.

 

Z- CLLI

The CLLI code that identifies the "Z" termination of the facility.

 

Channel Group Number

The Facility Designation code assigned to the facility where the circuit is contained.

 

Facility Type

The type of facility where the circuit is located (always displays a T1).

 

CAC

The Circuit Access Code assigned to the circuit.

 

Format

Identifies the type of circuit by circuit name and the specific format of the circuit. The formats are:

M or 1: Message Trunk

T or 2: Telephone- Numbered Special Service

S or 3: Serial- Numbered Special Service

C or 4: Carrier Facility Assembly

 

PON

The Purchase Order Number that authorized the request for the circuit.

 

Circuit ID

The unique identifier of the circuit. The Circuit ID varies based on the circuit format. See Circuit ID Format Tutorial for more information.

 

CKR

The circuit number assigned to the circuit by the Interexchange carrier.

 

CLO

The Circuit Layout Order number assigned to the circuit.

The first three characters of this nine-character code identify the Admin Area (two characters) and Order Class (one character); the last six characters are the serial number assigned to the circuit.

 

DV

The diversity code that indicates that the circuit is routed in such a way as to be diverse from other circuits. If no diversity code is specified, no diverse routing is assigned to the circuit. Some examples of diversity codes are listed below.

DV

D1

D2

 

CXR Type

Identifies the facility in terms of the multiplexing equipment where it is terminated at each end.

 

Due Date

Identifies the date that any assignment activity for the circuit is scheduled to be completed.

 

Activity

The type of assignment activity scheduled to be performed for the circuit. Activity types are:

 

Channel

The channel number that identifies the circuit on its T1.

 

Alternate

The alternate assignment indicator which identifies a given assignment activity as an alternate assignment to a cable pair or circuit that is effective only under certain conditions. Alternate assignment indicators are:

A: Alternate assignment

P or Blank: Prime assignment (non- alternate)

 

 

T3 Channel Detail

 

Channel

The channel number; a T3 contains 28 channels ( numbered 00001 to 00028); a T1 contains 24 channels (numbered 00001 to 00024).

 

ASGT/RSTN

The Assignment Restriction Code assigned to the T1 or circuit.

 

Cur Act

The activity currently being performed for T1 or circuit.

 

Inv Status

The inventory status. The inventory status codes are:

 

D

The diversity code which indicates that the circuit is routed in such a way as to be diverse from other circuits.  If no diversity code is specified, no diverse routing is assigned to the circuit. Some examples of diversity codes are:

DV

D1

D2

 

Circuit ID

When a T3 appears, this is the identifier of each T1 that comprises the displayed T3 (28 total).

When a T1 appears, this is the identifier of each circuit that comprises the displayed T1 (24 total).

 

Pend Act

Indicates any activity scheduled to be performed for the T1 or circuit.

The date any pending activity is to be performed is indicated in the next column, Due Date. Activity codes are:

A: Pending add or connect

D: Pending disconnect or move

R: Reuse, rearrange, rename

H: Hold (reserve)

$: Spare history

W: Working

(BLANK): No pending activity

 

Due Date

The date that a pending activity is scheduled to be completed.
