Perhaps everything isn't as spiffy as I thought When running zttool the card still reports as internally clocked
Zaptel.conf: # Global data span=1,1,0,ccs,hdb3,crc4 bchan=1-15 dchan=16 bchan=17-31 loadzone=se defaultzone=se And as pointed out by Peter I do get a lot of D-channel warnings ... Aug 9 16:21:25 NOTICE[1350]: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 1 And furthermore, now I've discovered that all channels seem to reboot from time to time Aug 9 16:15:18 VERBOSE[1350]: -- B-channel 0/1 successfully restarted on span 1 ... Could this be a HW problem with either the wiring, the PC or something else? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Peter Svensson Sent: den 9 augusti 2005 14:11 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] TE110P flashing red/green when PRI connected On Tue, 9 Aug 2005, Andrew Kohlsmith wrote: > On Tuesday 09 August 2005 04:32, Peter Svensson wrote: > > A bitstream is present at the receiver, though it is unframed and > > invalid (i.e. the receiver is seeing a transmitter that does not > > quite know what to transmit).

I believe you are correct regarding the red alarm. Red alarm is declared when a frame loss has persisted for more than 2.5s. It is a local alarm. A framing error is a neccesary consequence of a LOS. :-) Yellow alarm (Remote Alarm Indication) is sent when a frame error condition exists in the receiver. On a T1 it is sent in bit 2 of every frame (for D4) or through a pattern in ESF. For an E1 two separate errors indications are collectivly known as yellow alarm, loss of framing (sets the A bit) or loss of multiframeing (sets the Y bit). Blue alarm (Alarm Indication Signal) is sent when the remote end does not want to communicate. It is sent as unframed 1. > I seem to remember blue and yellow alarm being the same thing bu tit's > 6am here and the mind is very much foggy. :-) Blue alarm - the other end is either administrativly down or there is a disconnect between various layers somewhere along the receive path.
