ZEPHYR XPORT USER’S GUIDE

ISDN STATUS SCREEN

When using ISDN, one of the following status words will be showed on the default screen.

Ready: Line is initialized and is idle. If a SPID is required, and has been omitted, this could be displayed.

Connected: Line is in use

SPID Pending: If an external NT1 is used this may be displayed if it has not completely initialized. May also be seen if the line is misconfigured. If SPIDs are not required, and have been entered, this may be shown.

SPID Error: Indicates the SPID is incorrect. SPIDS are only needed with certain ISDN protocols used in the USA & Canada.

SPIDS are not used for ETS300 (Euro ISDN), INS 64 (Japanese ISDN) or AT&T Cust. PTP (AT&T Custom).

Inact: Indicates the external NT1 (if any) has not initialized to the line and nor is there an active NT1 on the S interface. NOTE that Euro ISDN (ETS 300) lines are permitted to go into this state, and will act normally when the time comes to dial (or a call is received).

For information on connecting the unit to ISDN, see Section 3.1.2 (ISDN Interface).

3.6 Connecting two Xports to the same ISDN circuit

Sharing ISDN in the USA & Canada

Sharing a single ISDN BRI circuit between two Xports is quite simple. The following steps will have you up and running in no time.

8-position 8-pin modular cable

6-position 4-pin modular cable

1.Connect the first Xport to ISDN in the usual manner (see Section 3.1.2)

2.Configure the first Xport's ISDN settings. You must use Natl I- 1 or DMS Cust ISDN service to share the ISDN circuit (AT&T Cust. PTP does not support this ability) for this to work. Enter SPID 1 and DN/MSN 1 (see Section 3.4).
