IP-SVR (IP Server Interface)

You can use the following Communication Manager SAT commands for emergency
transfer:
- set emergency-transfer on|off|auto - Use this to set emergency transfer to on
(not in emergency transfer), off (in emergency transfer), or auto (emergency transfer is
controlled by Communication Manager).
- status cabinet nn - Use this to verify the current setting of emergency transfer.
When the emergency transfer is set to other than auto an alarm is generated.
● Customer provided alarm device (CPAD) control
CPAD provides a contact closure across a pair of external leads that can be used to control
a customer-provided alarm device or an alarm indicator. The level of alarm (major, minor,
warning, or none) that causes a contact closure can be administered system wide. When
the alarm level matches the alarm level that was administered, the TN2312BP closes this
contact. When the TN2312BP is in emergency transfer, this contact is closed to activate the
CPAD.
● Tone Detection / Call Classification
The TN2312BP provides eight ports of tone detection and call classification. The
TN2312AP provides the same functionality.
● Tone/Clock functions
The TN2312BP generates tones and provides clock functions for the port network in which
it is placed. (The TN2312AP provides the same functionality.) This functionality is equivalent
to the TN2182B Tone/Clock circuit pack.
TDM-Bus Interface
The TDM bus is used by four different functions on the IPSI board:
1. When the Archangel module is activated, it uses the Spitfire2 device to be the bus master of
the TDM bus. The Archangel uses this interface to talk to the other port boards’ angels on
the TDM bus.
2. In angel mode, the Tone-Clock angel uses the Spitfire2 device to talk to an off-board
Archangel.
3. The Tone Generator uses the Spitfire2 device to put tones on the TDM bus.
4. The Tone Detector uses the NCE device to receive TDM bus time slots for tone detection.
Packet Bus Interface
When the PKT-INT module is activated, it uses the LANIS device to talk and listen on the packet
bus.
System Clock Interface
The Clock module uses the Spitfire2 device to generate clock pulses for the backplane.
