Aggregate

Configuration

When

we

use

the

term

aggregate,

we

are

referring

to

the

optical

section

of

the

multiplexer.

All

of

the

tributary

channels

(E1/T1,

LAN,

Order

Wire,

RS

‐

232)

are

multiplexed

or

"aggregated"

into

the

optical

fiber

transmission.

The

received

optical

transmission,

which

contains

all

of

the

multiplexed

signals,

is

de

‐

multiplexed

back

into

the

appropriate

tributary

channels.

To

enter

the

configuration

menus

for

the

aggregate,

select

the

"Optical

Port"

menu

item

from

the

main

menu

page.

The

menu

screen

is

broken

into

two

parts,

the

informational

part

and

the

configuration

part.

The

two

optical

ports

work

to

provide

redundancy

in

the

event

of

any

hardware

failure

or

fiber

cable

breakage

or

disconnection.

Type

:

Will

be

listed

as

either

"1

*

9"

which

is

a

fixed

transceiver,

or

as

"

SFP

"a

small

form

pluggable

transceiver.

Link

:

This

indicates

the

state

of

the

optical

link,

either

UP

or

DOWN.

DDM

:

Digital

Diagnostic

Monitor

is

an

optional

feature

of

SFP

modules.

An

SFP

which

supports

DDM

offers

additional

diagnostic

information

such

as

Tx

Power,

Rx

Power

and

internal

temperature.

The

fiber

multiplexer

is

able

to

read

and

monitor

this

information

if

available.

Working

Path

Status

:

When

1+1

optical

protection

is

utilized,

one

of

the

optical

paths

is

active

or

"working"

while

the

other

path

is

standing

by.

The

status

here

shows

which

optical

interface

is

providing

the

working

or

active

path.

bit

Error

Counter

:

The

multiplexer

maintains

a

constantly

running

bit

error

rate

channel

as

one

of

the

multiplexed

streams.

If

the

optical

path

has

transmission

errors,

this

stream

will

show

an

increasing

bit

error

count.

The

counter

register

can

be

cleared

and

then

monitored

over

an

extended

time,

looking

for

any

optical

transmission

errors.

Protection

Mode

:

Choose

the

mode

of

optical

protection,

non

‐

revert,

revert

or

manual

(non

‐

revert

default).

<

ALS

:

Enable

or

the

Auto

Laser

Shutdown

safety

feature

here

(disabled

by

default).

Loopback

Test

:

Take

care

when

doing

fiber

loopback

test

as

ALL

the

aggregate

channel

will

be

looped,

including

the

Ethernet.

If

an

Ethernet

port

is

connected

to

an

active

network,

the

multiplexer

will

create

a

broadcast

storm.

Please

exercise

care

when

performing

optical

loopback.

(See

next

page

for

loopback

details.)
