# dsx1CircuitIdentifier

Circuit identifier.

#### Syntax

DisplayString (SIZE 0..255)

#### Access

Read/write

#### OID

p.6.1.8.n, where n = the index number of the DS1 interface.

#### Details

The circuit identifier is represented by:

name-of-board_board-number_trunk-number

where:

name-of-board is one of the following:

Board type | Value
--- | ---
AG | AG_2000, AG_2000_BRI, AG_2000C
CG | CG_6060, CG_6060_4,.CG_6060_8 CG_6060C, CG_6060C_4, CG_6060C_8, CG_6060C_16 CG_6565, CG_6565_4, CG_6565_8 CG_6565C, CG_6565C_8, CG_6565C_16 CG 6565E, CG _6565E_4, CG _6565E_8
CX | CX 2000, CX 2000-16, CX 2000-32 CX 2000C-16, CX 2000C-32, CX 2000C-48

board-number is a two-digit number, starting at 0.

trunk-number is a two-digit number, starting at 0.

The circuit identifier matches the boardModelText object in the Chassis MIB, enabling cross-referencing DS1 interfaces between the two MIBs.
