We request the above number of ISDN Basic Rate Interface (BRI) circuits for use with the Telos
TWOx12 digital telephone system. This device interfaces audio equipment to digital telephone
services. It requires Circuit Switched Voice (CSV). We may also use this line for other equipment
which makes calls using Circuit Switched Data (CSD) service. 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.
TWO has an integral BRI terminal adapter which supports these protocols (see details on following
pages):
AT&T 5ESS: Custom Point-to-Point (5E4.2 or later), National ISDN-1
Northern Telecom DMS-100: Functional (PVC1), National ISDN-1 (PVC2)
Siemens EWSD: National ISDN-1
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-
pin/4-conductor RJ11-style modular jack (USOC SJA48), of which only the center two conductors will be
used.
Hunt Groups (please give us the option specified below):
❏ Please place all Directory Numbers for all BRI’s in a single hunt group Or
❏ Please create a hunt group with all Directory Numbers except (Specify) _________________________
