Hello All, I was wondering if I could do the following on asterisk... Get a T1 between 2 locations, and split it into a data channel of like 1024, and use the rest for voice channels. Has anyone done this and had it working well? Or would I need to get a csu that allows a split into two interfaces? Regards, Greg

Management just approved purchase of a Digium T100P and a T1 card for our Merlin Legend Switch. I will appreciate comments from anyone performing this installation before: - Which T1 card did you use in the Merlin Legend? - Did you require any special interface? (CSU/DSU, etc) - Any items to watch during installation. Also we will need to remove one of our old analog Trunk cards to accomodate the new T1 interface in the switch. This switch already has two T1 cards in it. I don't know much about restriction in the Merlin Legend Switch, but our phone tech told...

...about shorewall a few days ago and am quite impressed with how easy it was to create a powerful firewall. I set up a test system with a cable modem and it worked flawlessly. I''m going to be building a Router/Firewall for a new T1 that will be using a Sangoma WANpipe card w/ integrated CSU/DSU to connect to a T1. Has anybody done this yet, or do you know if it''s possible to use say the interface WANPPP1 or whatever it is called instead of a standard ETHx device? Thanks. -Ron

...uot;Integrated Access" product. From what they say it sounds like you can have audio dropouts on the voice channels when the data channels are being pushed to the max. I have never heard of this. It doesn't seem possible to me, and if at all, probably more of a limitation in the CSU/DSU than in the actual T. Isn't that what TDM is all about - giving each channel it's afforded bandwidth? What do all the telco people out there think? -- Kristian Kielhofner

Hi all, When configuring Asterisk with an ISDN card, it will at one point become necessary to select the LBO (Line Build-Out) value. This is an integer (0-7) that is determined by the length of the cable and is selected from the following table. Many of us are familiar with it: CSU (dB) DSX-1 (feet) ------------------------------- 0 0 0?133 1

This appears to be the case here. The machine is a Dell 11G server. I upgraded all the firmwares with dsu, BIOS was at latest already. After dsu, I upgraded the NIC option ROM with bootutil (I'm not using the builtin BRCM NICs, but an Intel X520-T2 card). That's all I can do on the hardware front. And it *still* shows the same behaviour. Moving tftp server it is then ...

Need help...I need to install a card to terminate 7 lines...I have not order the phone lines yet...I can either do analog lines 1FBs or order a fractional T1...any suggestions on what hardware would be easier to install and configure...also if I went with a T1...do I need an external CSU/DSU or anything or does it just plug into the T1 card...thanks.. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of asterisk-users-request@lists.digium.com Sent: Wednesday, February 01, 2006 5:41 PM To: Asterisk User L...

...asterisk systems and I'm looking for some suggestions as to what the best way to do this will be. The 2 systems are for 2 companies that share a single T1 line. The T1 line has 12 voice channels and 12 data channels. Currently, they are set-up as follows: T1 line from provider enters CSU/DSU and splits voice/data channels. The voice channels are sent to an ADIT 600 w/ 4 FXS cards. The ADIT 600 then breaks down the T1 voice channels into analog lines, of which 8 are fed into one phone system and 4 are fed into the other phone system. I have been thinking about throwing in 2 more ADIT...

...rver." You can't even call it a "voice communications server" because it does more than that! Is it a "Communications Server," or maybe a "telecom/datacom server?" I can see it now, yet more acronyms! How about this: Asterisk is an AVCS/DCS (kinda like CSU/DSU): Audio/Video Communications Server/Data Communications Server? We could have lots of fun with this one... :) -MC

Can anyone offer up a suggestion on a reliable and cost effective customer premise hardware setup to be able to take an inbound IP T1 and deliver a PRI interface to a remote office? Trying to reduce the amount of hardware required to implement this, right now we use a Cisco router to take the IP T1 in on a serial port and then we go Ethernet to a slimmed asterisk box with a single port T1

Hello all. I just received a TE110P and am trying to hook it to my Mitel 200SX has anyone successfully done this? My configuration is as follows.

We have a working PXE setup. I've tried to adapt it to UEFI as per RHEL6 manual, but the client won't boot. Strangely, tcpdump shows that the client tries to download all files via tftp from the dhcp server rather than the tftp server (they are different). next-server is pointing to the tftp server. Any clues?

...h a T1 card on your asterisk? If you want to use the T1 as 24 voice channels, the Telco is going to have to re-provision the T1 as a voice T1, because currently, presumably it is one big channel of data. You could have the telco do any combination of 24 channels, some voice and some data, if your DSU or router allows drop and insert of channels. It would then split the T1 into a "voice side" and a "data side", each with part of the channels available. Once you have a channelized voice T1, it can plug into a voice T1 card in your Asterisk, but typically can't do data an...

Hi list, I've browsed through the wiki pages and finally would like to get some answers from peple who perhaps had used such card. I have the sangoma s508 card. It has no CSU/DSU. It is an ISA card with DB9 and DB25 connectors (for RS232 and V34/X21/EIA interfaces). They claim it is a frame relay and syncronous ppp card. Can I use this card with asterisk in any way but without subscription to a Frame Relay account? Perhaps in similiar manner as T1/E1 between a channel...

Hi, I have a mint, like-new (used only once) Zhone Z-Plex channel bank for sale. It has 16 FXS and 8 FXO (part number: Z-PLEX-10-24S/O). It functions as a channel bank, router, and CSU/DSU, combining T1, analog voice, and data. D4, SF, and ESF line formats are supported with AMI or B8ZS coding. It has dual T1 jacks, one ethernet jack, one serial port, one V.35 port, and 24 analog pairs available via 50-pin Amphenol connector (I'll also include two Leviton 41600-I break-out boxe...
