IMPORTANT!
Each directory number will correspond to one SPID. You must enter them to reflect
this relationship. The DN corresponding to SPID1 must be entered as DN1 while the
DN corresponding to SPID2 must be entered as DN2.
If you experience problems only with incoming calls check your DNs.

HOT TIP!
Some versions of the Telos Zephyr and ZephyrExpress do not require that Directory
Numbers be entered. This is not true for the Telos TWOx12. You must correctly enter
these numbers for the system to work.
t
Deep Tech Note!
The actual physical B channels of the BRI line are assigned on a per call basis, with
the first incoming call assigned to the first B channel. However, the call setup
message on the D channel includes what number was dialed, and the Directory
Number allows the system to sort it all out.
w
IMPORTANT!
After you enter (or change) your SPIDs or DN’s you must restart the system to use the
new information. Therefore, once you have entered SPIDs, DNs, or MSNs cycle power
off and then back on. Then go to the ISDN status screen and verify “Ready” status for
all channels.
