We request an ISDN Basic Rate Interface (BRI) circuit for use with the Telos Zephyr Xstream
digital audio transmission system. This device interfaces audio equipment to digital
telephone services. It requires Circuit Switched Data (CSD). We may also use this device to
make calls using Circuit Switched Voice (CSV) service. We therefore request alternate
CSD/CSV on each B channel. Please advise us if there is a cost penalty for having both CSD
and CSV.
If you use IOC (ISDN Order Code) Capability Packages, please use Capability Package ‘S’ (unless
otherwise specified by the user). If you do not use IOCs, use the information on the pages that
follow.
Zephyr Xstream has an integral BRI terminal adapter that supports these protocols (see
details on following pages):
AT&T 5ESS: Custom Point-to-Point (5E4.2 or later), or National ISDN-1 or 2
Northern Telecom DMS-100: Functional (PVC1), or National ISDN-1 or 2 (PVC2)
Siemens EWSD: National ISDN-1 or 2
We can use any of the protocols given above. Please let us know which protocol you will
provide and the switch. We will provide the NT1 and need a U interface with 2B1Q line
coding on a standard, six-position/4-pin RJ11-style modular jack (USOC SJA48), of which only the
center two conductors will be used.
You may call the manufacturer of the Zephyr Xstream, Telos Systems, at +1 (216) 241-7225 for
any additional required information about ISDN compatibility. Ask for Telos Zephyr
Xstream Customer Support.
