Doesn't your provider monitor the lines and notify you of an outage?

FYI, "T2" services are NOT available anywhere, and the next step up is T3 (roughly 45Mbps, or 30xT1)... and there's no such thing as a "T7".
Is the "voice over" you refer to VoIP, or voice channels on DS0s?

I need help configuring my SOHO 91 router, via the CLI, for PPPoE client support.
Right now I have the router set up as a bridge, like this:
WinXP PC PPPoE client -> SOHO91 E1 bridged to E0 -> DSL modem -> PPPoE server (ISP)
I'd like to set it up as follows:
WinXP PC -> SOHO91 E1 -> SOHO91...
CIR + EIR = AIR
C stands for Committed
E stands for Excess
A stands for Available
If your PVC is 16K CIR and 32K EIR then your committed rate is 16K and your maximum "burst" speed is 48K.
Even if your port speed is 64K your site-to-site throughput can never exceed 48K.
The term "VPN" seems to be causing problems here.
VPN is any network that is shared. That can mean a Frame Relay VPN, L2TP over Internet VPN, MPLS VPN, ATM VPN... but not "IPSec VPN" since IPSec provides encryption, not connectivity.
The original post asks which is better...
If it's Cisco 805s that you're using then you're fine, provided that you have the right cable to connect the Smart Serial interface to the X.21 port on the BT CSU/DSU.
For business-grade videoconferencing, talk to Polycom (www.polycom.com), and forget about using the Internet for transport (use a private network: frame relay or MPLS).
Internet-based videoconferencing, and MSN Messenger (which actually uses MS Netmeeting) is fine for chatting with your...
Your frame relay service is made up of five basic components at each end of the connection:
1. router
2. CSU/DSU
3. local loop
4. frame relay port
5. frame relay PVC
The local loop is likely 256K, which is actually fractional T1 or E1 (depending on where you are in the world).
The port is...
High Speed Frame Relay (>DS1) works well as it avoids some of the complexity of FRATM (Frame Relay to ATM interworking) when connecting low-speed (DS1 or lower) to high speed sites.
ATM is better for deterministic point-to-point throughput, and will scale past DS3, but does not work well at...
With the info you've given I would suggest the following:
- 1721 + external 56K DSU (Adtran or Motorola) for branches
- 2611XM + external T1 CSU/DSU (Adtran or Motorola) for head office
10.x.x.x address space, subnetted however you see fit
dynamic routing via RIP (for simplicity) or OSPF
