ZEPHYR XPORT USER’S GUIDE

When placing ISDN “Zephyr mode” calls between Xstream and my Xport, I get no audio or lock.

Zephyr mode calls from Xport require that the Xstream’s codec settings be configured as follows:

Xmt = AAC-LD mono 64; Rcv = AAC-LD 64; Bit rate 56 or 64; Sample = 48 kHz

I can’t place or receive calls using ISDN.

If you are using the (2-wire) U interface, what is the status of the U Sync LED located next to the ISDN U interface jack.

If this LED is flashing slowly disconnect any equipment attached to the ISDN S interface jack and restart the Xport.

If this LED is flashing quickly (flickering) try another cable between the ISDN jack and the Xport. If this does not help, suspect the ISDN line.

If the LED is illuminated continuously, this indicates the “layer 1” connection has been established between the Xport and the ISDN switch (or an active U repeater). In this case check the line status on the main status screen (see Section 3.5 for more on the ISDN line status). Go to the ISDN menu and check your SPID (if required) and make sure that the correct Directory Number is entered. Check the Telco setting and then restart the unit.

If you are using the (4-wire) S interface, check the status indicators on the external NT1.

If the NT1 shows normal status check the line status on the main status screen (see Section 3.5) for more on the ISDN line status). Go to the ISDN menu and check your SPID (if required) and make sure that the correct Directory Number is entered (if required). Check the Telco setting and then restart the unit.

If the ISDN status shows INACT try placing a call to the unit. Does the status change when a call is attempted?
