Does phone equipment see the Adtran 924 PRI as a true PRI? Ie. can this be used in place of a true PRI? Are there any hangups I should know about? I was just going to use this to provide PRI to a customer over SIP rather than have to run a PRI as well. Any advice with the 924? -Eric
Yes. This is the main use of the 9xx series. On 1/2/2011 8:35 PM, Eric Hiller wrote:

Yes, it works well. We have several dozen in service. Many options re switch type, name display, user/network, etc. Very flexible box. No real issues. North America only. No E-1, 120 VAC mains or 48-volt battery (intended as backup but you can power the box from it.) Unless you also need numerous analog ports, the 904 is much less expensixe and does PRI just fine.
Any advice with the 924?
They work well, no real problems. Be careful to set clocking in a sensible manner. If you feed the 924 from a data T1, clock from line on that and pass it through to the PRI. If the PRI is the only T1 in the system, clock internally. If the PBX also has a PRI from another carrier, clock from the customer PBX and fall back to internal. Ground the Adtran and the PBX to a common earth ground. This is especially important if you use the analog ports. Strangely, Adtran includes wall brackets with these but no rack ears. You can order them separately. The 904 and 908 are too narrow to conventionally rack mount. -- Jay Hennigan - CCIE #7880 - Network Engineering - jay at impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV
The Adtran 90x series is a swiss army knife of VoIP. They can do just about anything. We have a bunch in service, love them. 10 year warranty is pretty nice too ----- Original Message -----

I've got quite a few in the field that are doing PRI and Voice T1. They work great provided that the customer's PBX vendor will give you the correct config. If you use a TA900E series router you will need a T1 Crossover cable when you connect to the customer's PBX. I spent an hour trying to figure that out after we upgraded a customer from a TA908 to a TA908E late one evening. :) Richey -----Original Message----- From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Eric Hiller Sent: Sunday, January 02, 2011 9:35 PM To: voiceops at voiceops.org Subject: [VoiceOps] Adtran 924 PRI Does phone equipment see the Adtran 924 PRI as a true PRI?

Great box and you can't beat the price, handles both PRI and CAS T1. Also supports T.38 on the analog ports and works quite well now that the software bugs are worked out. We have well over 100 of these units deployed and have no complaints. ---Chris On Jan 2, 2011, at 9:35 PM, Eric Hiller wrote:
