Thanks Scott

>>The cable is easy: each end of the connector is one pair, with the pins being the top-most and bottom-most pins on either side (pins 1&9 and pins 8&15 ... crossover 1->8, 9->15).

Could you please refer me where have you found this ? and Are you talking about DB15 to DB15 ? because in the link that I have posted :

http://puck.nether.net/pipermail/cisco-nas/2003-December/000421.html

is different to what you have mentioned

Hi,

that is not correct. After you have made the cable as indicated, just configure as detailed at:

http://www.cisco.com/en/US/partner/products/ps6350/products_configuration_guide_chapter09186a00800ca716.html

and PRI back-to-back will work without need for a switch.

Thanks P

could you please tell which one of those links that I have posted can be used to make a DB15 to DB15 cable, because I can see they have been using different pinouts assignments

Hi, any guide than mentions DB-15 is good, just cross tx and rx and is done.

Thnaks P

What confusing me is : when I compared between the link from cisco

http://www.cisco.com/en/US/products/hw/iad/ps497/products_installation_guide_chapter09186a008007e299.html

and the link below :

http://puck.nether.net/pipermail/cisco-nas/2003-December/000421.html

In the link from cisco (Table C-7: EI Interface Cable Pinouts) uses 6 (while other uses 4) pinouts :

Pin 8 --->1

Pin 15 --->9

Pin 7 --->2

Pin 9--->3

Pin 2 --->11

Pin 10 --->4

While in the other link uses 4 pintouts

DB-15 ----- DB-15

1 ----- 3

3 ----- 1

9 ----- 11

11 ----- 9
