There is an option called NFAS, using this you can use one B channel for several cards. 3Com supports one B for 14 spans on the DSP, however you should consider having two B support the entire chassis one main and the other backup. -V ----- Original Message ----- From: "Terry Kennedy" <terry@olypen.com> To: <usr-tc@lists.xmission.com> Sent: Wednesday, June 05, 2002 6:51 PM Subject: [USR-TC] PRI and b channels
With out coming off as a junior idiot here, I need to ask a question about PRI. In our town they said they would never get PRI so I never read most of the posts here concerning them. We used CT1's and I know (basically) how they work. Now they have PRI and I am converting -- Ok, so enough rationalizations for asking stupid questions.
Here's the question: Do I lose 1 channel on every span for the b-channel or does just one of the cards in the rack need to lose the channel?
Qwest says that they support 11 spans with one b-channel, so it made me curious on the 3com equipment.
Anyone have a quick run through on setting these up or just a link I can read somewhere?
These are DSP's by the way.
Thanks, Terry Kennedy
