Basic T1 Setup with AdTran Router

Jump to solution

Our company has recently purchased a T1 line, we were given an AdTran 3430 and IP information and basically told we are on our own to set it up.  If anyone can offer a real straightforward setup procedure it would be greatly appreciated.

Where would all this info go, I'm not familiar with the AdTran interface or T1 lines at all for that matter.

Customer’s WAN connecting to Network: xx.xx.xxx.138 255.255.255.252

Default gateway: xx.xx.xxx.137

Customer’s static IPs:  xx.xx.xxx.104/29

Network: xx.xx.xxx.104 255.255.255.248

Usables: xx.xx.xxx.105 – 66.84.147.110

Broadcast: xx.xx.xxx.111 255.255.255.248

Thanks in advance for taking the time!

Re: Basic T1 Setup with AdTran Router

- The following guide provides detailed step-by-step instructions on how to set up an AOS router for T1 internet access : Configuring T1 and E1 Internet Access in AOS

The guide also explains how to set up the NetVanta 3430 depending on whether you want to use it as a firewall or whether you plan on using an external firewall.

You will need the following list of information before you can properly configure your AOS router. Some of this you have gathered already. Only your service provider and your Network Administrator can provide you this information:

1.     Public/WAN IP Address and Subnet Mask

          Sometimes referred to as “Customer Serial Address”

          Customer’s WAN connecting to Network: xx.xx.xxx.138 255.255.255.252

         Default gateway: xx.xx.xxx.137

2.     LAN IP Address

             The router’s address on the LAN. This could be a private IP address if you plan on using the 3430's firewall or one of the usable static IPs you received from your provider.

          Usables: xx.xx.xxx.105 – 66.84.147.110

3.     Framing (ESF or D4) Format

          Coding (B8ZS or AMI) Format

          Data DS0s (Channels)

          You must know specifically what channels, not just a number of channels

          (Example: 8 through 14, not just ‘7 channels’)

4.      Layer 2 Encapsulation Type (PPP, HDLC or Frame-Relay)

          For PPP Connections:

          a.) Username and Password for Layer 2 (not normally implemented)

          For Frame-Relay Connections:

          a.) DLCI Number for Internet Access (Example: 16)

Please do not hesitate to let us know if you have any further questions or issues.

Thanks,

Noor

Re: Basic T1 Setup with AdTran Router

If it helps to put this in context, here is a config snippet from a similar router with a HDLC connection (Its E1 as opposed to T1 but will be essentially identical otherwise).

We are using all available channels on the E1 and you can see the hdlc interface cross-connected to the E1 interface.  In this case I didn't need to change any of the E1 framing or coding types from their defaults - you may have to - see Noor's linked document for more info.

You will also need the ip route command to ensure the default gateway is pointing to the ISP's router.

For this example I have also assumed the first available IP in the LAN range range as the LAN ip address.

interface eth 0/1

  description LAN Connection

  ip address  X.X.X.105  255.255.255.248

  no shutdown

!

interface e1 1/1

  tdm-group 1 timeslots 1-31 speed 64

  no shutdown

!

interface hdlc 1

  description WAN Connection

  ip address  X.X.X.138  255.255.255.252

  no shutdown

  cross-connect 1 e1 1/1 1 hdlc 1

!

ip route 0.0.0.0 0.0.0.0 X.X.X.137

For a PPP interface the document noor has already linked to will show you how to set up that type of interface.

Remember to change the default username and password on the router and it is good practice to limit direct connections to the router to your management network - you can find information on the stateful firewall here - Configuring the Firewall (IPv4) in AOS
