What kind of T1 lines are supported?
The logger supports all US standard T1 lines as well as Japanese formats. AMI, B8ZS, SF, ESF line codes are supported. FT1 lines will work fine, just disable logging on the data and unused channels. Question: How many channels can I record? Answer: Since the logger has two T1 framers, you can record up to 48 channels. If you have a PBX programmed to output audio via a T1 card, each of the 48 channels can be recorded individually. If you are bridging an outside T1 span in half-duplex mode, you can combine the audio from the East and West sides of the line automatically. In this configuration, you’ll record 24 channels. Question: Does it support PRIs? Answer: Yes, ISDN PRI’s are supported. You’ll record 23 channels per trunk on a PRI. The 24th channel carries signaling and can be recorded to a raw data file. VOX operation is used for start/stop control. DTMF and CID are currently only decoded when transmitted in the voice band. Question: How can I connect to my PBX in “loop” mode? Answer
