Currently installing pair of 2610XM rtrs with Drop & Insert cards (VWIC 2MFT-E1-DI) between them.
At each side there is PABX connected via E1 to Drop&Inser card, and 2Mbs leased line between locations.
Configured 15 CH for data and 15 CH for voice.
Data works fine.
Voice services work fine as well, BUT!!!
- When trying to use analog modems between locations its not working
- When trying to send fax between locations, its hardly working (i.e. 1/10 success & even then copy is hardly readable).
All problems not present when I bypass routers and 2Mbs leased line with 120Ohm cable.
Any knowledge about similar problems?
Any tip for sorting this kind of problems, or this is by default behavior for such setup?
