PRI 2CE1B and DB-15 cable to simulate ISDN connection

[wolseley]

I am looking to do a test at a lab (to simulate a real life design). I have got two routers, each router has got PRI 2CE1B interface card.

Can I connect these tow router by using :

E1 Interface Cable for 120-Ohm, Balanced Connections (with DB-15 Connector),to simulate ISBN PRI connection ?? or I have to buy an ISDN simulator for this purpose ?

Similarly If I want to simulate BRI between two routers (that have BRI Interface card) , can I use a specific cable for that ? or also I need to buy simulator ?

Before worrying about cable, you need to make sure your equipment can support network emulation.

A network switch provides an line termination "LT". User equipment supports network termination "NT".

SO you jmust be able to configure one of your cards for LT or it won't talk to the NT card.

As far as cables goes, PRI will work with reversing cables. For 110 Ohm this means a cable that swaps pins 1/2 with pins 4/5.

If using coaxial connections you must swap XMT and RCV.

Good luck

How can I make sure that with cisco routers 3640 ?

Thanks

You might ask on the Cisco forum. Some equipment does, but most does not.

Good luck.

Thanks for that
