Configure 2620 for Local T-1 Facility.

[oceanweb]

We recently moved our network to a new building and our new provider furnished us with an Adtran 608 router (no customer access). I would like to replace this unit with the 2620 from our old network so we can administer the router locally.

Can someone provide step-by-step instructions for the setup of the 2620. It has one FastEthernet interface and one Serial interface. Our office has a T-1 with 64 public IP addresses (Subnet 255.255.255.192). The loopback device is currently connected to the Adtran router and our network is up and running.

I have the WAN IP address information and our IP address information and know how to get to the initial setup screen of the 2620 using Hyperterminal. Our provider gave us the green light on replacing the router.

Can some give me step-by-step instructions from here.....
------------------------------
rommon 1> confreg 0x2142
rommon 2> reset
would you like to enter the initial configuration dialog? YES

---------------------------------

Any help would be appreciated!

Thanks,
Greg.

UPDATE::::::

I contacted my provider and they said they will provide any parameters that are needed but they can't walk me though the setup of the router.

Here's what I've got (on my own) so far.......(can't ping outside addresses)

-------------------------------------

Router#show running-config
Building configuration...

Current configuration:

version 12.0
service timestamps debug uptime
service timestamps log uptime
no service password-encryption

hostname Router

Any help will surely be appreciated!!

If your provider gave you an Adtran 608 do I assume this is a bundle T1 with voice and data?

If so the internet pipe will be fractionalized lets says 512k (8 channels). This would normally be setup on channel 17 thru 24 for example.

Have the provider activate the DSX-1 port on the Adtran and connect it to the Cisco router and program. You will need WAN ip/subnet, LAN ip/subnet and gateway. You also need to find out if this on a point to point or frame relay circuit.

Check these out and advise.

Our T1 is full data......I was on the phone with ISP all day yesterday and they are no help. According to them, My 2620 is connected to a 7206 that's configured with encapsulation frame-relay IETF.

This is my current config based on their recommendations. When I boot the router, I can ping the serial interface for a few seconds but then it changes it's state to "down".

If anyone can help with this, it would be greatly appreciated.

Router>en
Router#conf t
Router(config)#int s0/0
Router(config-if)#no encap frame-relay ietf
Router(config-if)#no frame-relay lmi-type ansi
Router(config-if)#^z (which is control-z)
Router#sh run

Do this and post the result---this should take the frame relay encapsulation config off and put it back to the default (hdlc, I think).
When you say you can ping the serial interface for a few seconds, are you talking the local or remote (.169)?
What is on the other end of the serial, another Cisco router? The one with 70.43.166.169---also, is the mask of this interface 255.255.255.252?
What is connected to the fa0/0 interface? Your lan, I hope...if so, why are you using a public IP address?

Please be a bit more specific, especially with the entire topology of your network.

Got is working......

ISP finally gave me correct serial config. Did speed test using

http://www.speakeasy.net/speedtest

and now showing 1293kbps up and 1022kpbs down.

interface Serial0/0
ip address 70.43.166.170 255.255.255.252
no ip directed-broadcast
encapsulation frame-relay IETF
no keepalive
frame-relay map ip 70.43.166.169 16

Thanks for the help guys.....

Greg.

oh---so it is frame relay...you just didn't have a dlci mapped.
