Field Description

PORT NUM

Port number.

MDA DESCRIPTION

This field describes the MDA:

Quad OC-3c SM — quad port OC-3c single-mode fiber

Quad OC-3c MM — quad port OC-3c multimode fiber

OC-12c SM — single port OC-12c single-mode fiber

OC-12c MM — single port OC-12c multimode fiber

SCRAMBLE ENABLE

Parameter that enables/disables the scrambling option.

FRAMING MODE

Indicates the framing for the port, either:

sonet, which means the Synchronous Optical Network
format, the standard format in North America.

sdh, which means the Synchronous Digital Hierarchy
clock format, the standard format in Europe.

MAX-BITS VPI

For OC-3c, 11 bits split between NumVpiBits and
NumVciBits. NumVpiBits cannot exceed 6 bits for OC-3c.

For OC-12c, 13 bits split between NumVpiBits and
NumVciBits. NumVpiBits cannot exceed 8 bits for OC-12c.

MAX-BITS VCI

This field is read only. It takes remaining bits from
NumVpiBits. For example, if NumVpiBits is 3 for OC-3c,
then NumVciBits is 8.

CLOCK SOURCE

Indicates whether the Clock Source is either:

line

internal

LOOPBACK MODE

Indicates the loopback mode::

off

internal

external
