hi,can anyone tell me how to take loop test on HTU E1 Leased line modem to test physical connectivity
I have a couple of 3745 router and I would like to join them with a DS3 link. Can someone tell me the difference between a NM-1T3/E3, a NM-1HSSI and a NM-1A-DS3 cards ? In what do they differ from one another ? Thanks.
