Okay a bit clearing about E1: E1 is Linespeed 1984 or 2048. Unchannelized E1 means clear bandwidth of 2048 unstructured channelized e1 means trunk is divided by 32 Timeslots; Timeslot 0 is used for syncronization of the other timeslots and cannot be used for data transmissions. e.g.: unchannelized e1 is "point-to-point" but channelized e1 can mean "point-to-multipoint" Hope that clear it a bit Jan Czmok - --- Jan Czmok Senior Network Engineer IPF.NET Service Provider GmbH -----BEGIN PGP SIGNATURE----- Version: 2.6.3ia Charset: noconv iQCVAwUBNgIxQOxodCrDtTgJAQGXWwQAjabU1JZTR6oRlpdnxTDzvPghOJ39Fcoo QszPwyis37VCPGt/R9+VxfyJwhVOhsylgLoqrXbE/wlVnVCQrr70DzI1QPnQHDQk XdNokz0bwVrAfCvJBgQiimiHVEoDNmoVPP37c5MFH70JlLpbya0VCjz14wiLNWqW aaLHZWijCjc= =bJEi -----END PGP SIGNATURE-----
