| I did something similar in Suriname. However, we were interfacing the Dual Loop PRI cards to a Cisco router. If you are converting A-Law to Mu-Law, you need to make sure you have Package 167 (T1-E1 Gateway) in that Option 11C or you will have noise. We fought it for hours before I turned the package on and it cleared it. Everyone thought it was the Cisco and it wasn't. |
