Re: 3640 as a AS5300 backup

jpelletier · ‎03-09-2002

Hi, I want to know what type of cards I need for a spare 3640 to function as a backup for a AS5300,with one PRI. Approx cost?

Hi,

Depends on what mode of backup you are looking for, ie, isdn (BRI) or analog (POTS).

If you have a blank chassis, will need a LAN/WAN combo card, have options for ethernet or fastethernet: NM-1E2W / NM-2E2W /NM-1FE2W /NM-2FE2W.

WAN connectivity for backup can be achived using one of the following WIC cards (that can be inserted as daughter cards in the LAN/WAN combo card)

WIC-1B-U <===for isdn

WIC-1AM / WIC-2AM <===built in modems connecting to POTS lines.

Thanks,

Mak.

Well actually it would be for both isdn and dial-up users.

Hi,

Ok, looks like you need a standby RAS (equivalent to the as5300). The 5300 is supporting isdn as well as modem calls comming on the PRI.

The 3600 can do that functionality using the following cards:

1)NM-1FE1CT1-CSU.....One-port 10/100BaseTX Ethernet with one-port T1 PRI/Channelized with integrated CSU

2)NM-24DM ....Network Module with 24 digital modems (could be in multiples of 6, ie , NM-6DM /12DM/18DM)

Thanks,

Mak.

Thank you for your help

I agree with Mak, but if you are located in Europe you'll need a E1 instead of the T1 and the NM-24DM can be up to NM-30DM. The Digital modems allow you to recieve analog callas (POTS), and if you have only one PRI in that case consider getting something like NM-18DM, since there is very little possibility that you'll recieve 30 concurent analog calls on your backup router, and the digital modems network module is quite expensive.

Hope this helps
