Ok, I did some checking around... Right now I'm a bit confused with terms. Let
me try and figure this out.
First, what I have installed by the local telco is a 2meg line received in
G703/G704 with timeslots 1 and 2 used by a 128k link.
In another POP, we have a CISCO 4500 with a E1 controler that takes this line
and groups the two timeslots to give a serial interface. The Cisco calls this
type of line Channelized E1. This interface can have more lines to other places
that come in on the other timeslots. For ex, I can have a 128k line using TS 1
and 2 to the backbone, another 64k line to a customer in TS 4, and yet another
64k line to another customer on TS 5. Cisco would create 3 Serial interfaces by
grouping these channels.
That's the setup I want to do with the PM3.
Now this is what I interpret from the Livingston docs...
The PM3 can have 5 different types of lineX: ISDN (ISDN primary rate
interface), T1 (used in the states), E1 (Europe 2meg line), Fractional (both E1
.and T1) and Inband (Chann T1 in the states).
I would assume that I should configure the line1 (in my case) with set line1
fractional and then do set line1 group 1 channels 1 2 to get my w32
interface to the backbone...
But if I do that, the line is always down... If I do a set line1 e1 the line is
up.
hmms... Fractional (E1) and Channelized E1 seem similar... I dont really know
the difference between the two... Maybe someone can enlighten me?
Thanks in advance
