2.5 ALARM RELAY UNIT ALARM GRID INTERFACE
The 4000XA, 4180, and the 4280, each provide a standard wiring for activation of the
alarm grid should the hardware encounter a fault condition. The fault conditions include
a total loss of power to the device. The alarm grid interface may be wired for normally
open or normally closed connections.
2.6 Peer To Peer Secure Socket Cryptography
The xxxx will support peer to peer communications using secure cryptography. This is
important for Internet Protocol (IP) networks where the contents of the peer session is to
be protected from network sniffer devices. The cryptography feature is selectable on a
per port basis, and both session endpoints should be set identically. The cryptography
key selection is dynamic, and automatic.
2.7 X.25 Mediation Features
The 4280 has thirty two instances of the X25PAD mediation application.
The 4180 has sixteen instances of the X25PAD mediation application.
The 4000XA has sixteen instances of the X25PAD mediation application.
The 4284 has four instances of the X25PAD mediation application.
The 9480 has one instance of the X25PAD mediation application.
Use of the X25PAD application is exclusive of any other vertical service application (e.g.
E2AHOB) or feature package.
Each of the serial ports on these devices may be connected to a (B)X.25 interface. The
X25PAD mediation application allows a telnet client to interface on a per VC basis. In
addition, X.25 pass-through for VC aggregation is fully supported. Each VC may be
individually configured as a PAD or a PASS-THROUGH interface. A specialty interface
for the MacStar operations system is supported. The Record Boundary Preservation
protocol is supported. SVC hunt groups across X.25 lines are specifically supported
allowing fault tolerant X.25 links to be established. The (B)X.25 session layer is
specifically supported via an API.
2.8 Time Slot Router (TSR) Features
The 4180 provides one RJ48C for a TSR interface. The RJ48C supports T1, E1, or J1
software configurable. Each time slot may be uniquely routed on the IP WAN. Individual
CODECs may be installed for load optimization. HDLC time slots may be terminated for
use by 6xxx applications, or for routing to serial ports.
2.9 E2A Head of Bridge Features
The 4280 does not support the
E2AHOB mediation application at this time.
The 4180 does not support the E2AHOB mediation application at this time.
The 4000XA does not support the E2AHOB mediation application at this time.
The 4284 has four instances of the E2AHOB mediation application.
