First you can try with a straight Ethernet cable. It it doesn't work, 
you will need to buy or make a crossover RJ-48 like the shown below:

T1 or E1 PRI crossover cable:
(Taken from 
http://www.chebucto.ns.ca/Chebucto/Technical/Manuals/Max/max6000/gs/cables.htm):

RJ48C/RJ48C Install this cable when the WAN interface transmits on pins 
5 and 4 and receives on pins 2 and 1. Refer to Figure C-2 
<http://www.chebucto.ns.ca/Chebucto/Technical/Manuals/Max/max6000/gs/cables.htm#17423> 
and Table C-5 
<http://www.chebucto.ns.ca/Chebucto/Technical/Manuals/Max/max6000/gs/cables.htm#30240>. 


Figure C-2. RJ48C/RJ48C crossover cable Table C-5. RJ48C/RJ48C crossover 
cable specifications

That'll do.

Cheers,
