Re: [asterisk-users] Use modprobe to find E1/T1 jumper setting onPRI card
Thanks Shaun. Unfortunately, I am still using zaptel. Is there a similar command in zaptel? -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users- boun...@lists.digium.com] On Behalf Of Shaun Ruffell Sent: Thursday, 30 September 2010 1:00 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] Use modprobe to find E1/T1 jumper setting onPRI card On 09/29/2010 02:52 AM, Lee, John (Sydney) wrote: Do you mean that if I could define 30 channels in span 1 for example, then span 1 is set to E1?

Do you mean that if I could define 30 channels in span 1 for example, then span 1 is set to E1? If not, then it is T1.

If your card says it has 30 ports then it is on, if it only says 24 it is off.

I want to find out the jumper settings on the card without opening the box which will cause down time.

Civilised countries manage to squeeze 30 B-channels and two D-channels onto an ISDN line by using trinary encoding, where three trits represent four bits. DC balancing is achieved by using two (equal and opposite) 3-trit representations for each of the nybbles represented by unbalanced symbols, and sending one or the other depending whether the imbalance is positive or negative. This gives 33% extra capacity as compared to simply sending ones as positive or negative in strict alternation, hence 30 + 2 aot 23 + 1. -- AJS -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
