Hi, yes it's for connecting an PRI line. In fact i already have one PRI connected to a 'real' PRI line,provided by France Telecom. But this one is a little bit special, it's for connecting to this kind of box: http://www.oneaccess-net.com/en/one400.htm Which is a SDSL/PRI gateway (yes, i asked for a direct SIP/H323 connection, but "it's not in our product line" was the only answer ..). Until know the L1 link doesn't goes up, so i'm looking for every bit of info i can use. The FT line is configured like that: span=1,1,0,ccs,hdb3 bchan=1-15 dchan=16 And work quite well, i've duplicated this for the access thru the One400 box: span=2,0,0,ccs,hdb3 bchan=32-46 dchan=47 With no luck until now. I'm reading the one400 manual, and here are the defaults setup for the PRI interface: CLI(config)# interface pri 5/0 CLI(config-if)# physical-interface E1 CLI(config-if)# framing Df CLI(config-if)# linecode hdb3 And here are the available framing: CLI(config-e1)# framing {none | df | mf | emf} Specifies the framing type. None: no framing. Only used for CES / unstructured mode Df: double frame, no CRC4. For E1 only. (Default value) Mf: multiframe (CRC4). For E1 only Emf: extended multiframe (CRC4). For E1 only. Sf: Super-frame (for T1 only) Esf: extended super frame (for T1 only) I also found this: The ONE 400 supports CCS mode (transport of signaling messages over a D channel). CAS (Channel Associated Signaling) mode is not supported. However there is no references to this 'double frame' mode in the dahdi/system.conf span configuration options # framing:: # one of 'd4' or 'esf' for T1 or 'cas' or 'ccs' for E1 and BRI. # 'd4' could be referred to as 'sf' or 'superframe' _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
