we know that 1841 router can't support voice terminations, but when one comes to the dynamic conf tool to add 1841 WIC/HWIC/VWIC Slot options, one finds that 1841 does support VWICs (xMFT-T1/E1 or G703...)
the question now is how it comes that 1841 does not support voice termintion while supports VWICs, aren't VWICs for E1/T1 voice calls terminations to pstn?!
u are right p.bevilacqua, in the description of (for example vwic-mft-xx) it is a trunk voice/wan int card. thanks
and here is 5!
can i ask u two more related questions:
1: what is the difference exactly between G703 and other T1/E1 cards under VWIC-xMFT, i know that it is a matter of interface type, but are there additional features in G703 not available in other T1/E1 cards, is it correct that G703 supports channelized E1 while others don't?
2: what is meant by DI (drop and insert)feature in E1 T1 cards, i read about it but didn't get the idea yet. could u please clarify this to me?
in reality Drop and Insert does more than that, it let's you have multiple interfaces doing TDM MUX, while what you have described is simple termination.
Also consider, that in E1 world, mixed voice/data applications on the same circuit are very rare for multiple reasons. First, generally telco is unwilling to do such things because are too complicated to provision and configure. Second, using E1 generally the signalling scheme is ISDN PRI, that is always on channel 16. That means you don't have much flexibility like in T1 CAS, where telco and users are quite comfortable with the concept of timeslot. So the D&I application are more common on T1 than on E1.
