CO/Exchange Line Interface - ISDN BRI

The System supports ISDN BRI with the VB-44530 ISDN BRI interface unit. The VB-44530 is a T-
Point ISDN-BRI that supports 2 B (bearer) channels and 1 D (data) channel (2B + D; 192kbps). This
unit connects to an ISDN Data Service Unit (DSU). Point-to-point and point-to-multi operations are
selectable.
The ISDN-BRI supports enblock setting and enblock setting at the sub-address.

CO/Exchange Line Interface - ISDN-PRI

The System supports ISDN-PRI with the VB-44540UK ISDN PRI Interface unit. The VB-44540 is a
T/S-Point ISDN-PRI that supports 30B (for UK) or 23B (for HK/TW) (bearer) channels and 1 D
(data) channel (30B + D; 2M) (23B + D; 1544kbps). This unit connects to an ISDN DSU.
ICX: Up to 3 units may be installed in a cabinet if you use full channel (30B + D) or (23B + D or 24
B). A maximum of 18 units may be utilized in a fully equipped system. When all 30 or 24 channels on
a unit are utilized, 3 slot positions are required.
S-ICX: A maximum of 1 ISDN-PRI unit may be installed ina S-ICX system with CPC-HS. Up to 2
ISDN-PRI units may be installed in a S-ICX system with CPC-HM.

Data Security

Description
If you are using a line for data (modem connections, etc.), Data Security makes it possible to prevent
interruptions. Data Security can be implemented for either all phone use or outside line use.

Day/Night System Mode

Description
Day/Night System Mode enables you to switch the System between two Day modes and a Night
mode. These modes determine incoming call handling, Toll Restriction Service (TRS) call handling,
and attendant group support.
While in a Night mode (generally used at night or any time when your office is closed), incoming
calls can ring at selected extensions (e.g., a night watchman's extension or an extension connected to
an answering machine). Outbound calls can be restricted to certain phones. Calls can be directed to a
nighttime attendant group instead of the normal daytime attendant group.
The System provides one Night mode for night call handling. However, there are three night feature
access codes (Night, Night 1, and Night 2). These three codes may be used to provide different two-
way Voice Processing Unit messages (i.e., Night may select one message, Night 1 may select a
different message, and Night 2 may select a third message.)
