Hi folks,
Here goes with my first post… treat me gently please as I’m new to this game and learning fast!
Back ground… (all of technology I’m very familiar with!).
1. Until a couple of years ago I had a ‘kilostream’ service from BT in the UK connecting a ‘radio studio’ at ‘A’ to a ‘remote booth’ at ‘B’ over a distance of 40 miles. The kit in use was a BT NTU connected to a Musicam CDQ1000 audio codec via x.21 cabling. This gave me a permanent, always on, 64Kbit/s Mono bi-directional audio circuit.
2. The above was update due to cost with the ‘kilostream’ service being replaced by ISDN2. The NTU was replaced by an ISDN Dialler connected to the Musicam CDQ1000 audio codec via X.21 cabling. This gave me an ‘on-demand’ 64Kbit/s Mono bi-directional audio circuit.
3. I’m about loose the ISDN service because BT are to upgrade the local exchange at ‘B’, removing ISDN as there are few users plus they’ve discontinued the product!
So what I was thinking was this…
Use TCP/IP as the carrier via my ISP and get a ‘black box’ to convert from TCP/IP to X.21 so I can keep all my existing Musicam CDQ1000 audio codecs, plus revert to having a permanent, always-on, circuit again!
So existing kit:
Musicam CDQ1000 X.21 audio codecs – Studio & remote
Cisco 1760 rack mount ‘router’ with WIC-1 ADSL & WIC-1B S/T (ISDN for backup) – Studio server room
Netgear DG834G ADSL Router – Remote Office (single PC connected)
The plan…
Replace C1760 WIC-1B S/T (remove ISDN) with a WIC-1T Serial - Studio
Acquire a C1721 Desktop ‘router’ with a WIC-1T Serial - Remote
Configure C1760’s WIC-1T Serial talk to C1721’s WIC-1T via the FastEthernet to the Netgear?
Having read a few post on various forums It think I’m going to have to get the script on C1721 remote to initiate a VPN? The studio has a static IP address while the remote does not. The PC in the remote office VPN’s in to the server at the studio when the users logs in.
Is it possible and how do I do it?
I’ve a very basic knowledge of Cisco’s coding enough to get the C1760 talking to my ISP and surfing the internet and for port forwarding to my admin server for email and other stuff.
Awaitng some insight!
