- Provides physical connections for E1/Tl WAN interfaces.
- 893x and 8000-IF cards are split, allowing maintenance without service interuption
- Range of Interface Cards to support low-end or high-end functionality
- Optional integral modem for remote connectivity.
- Serial port for local VTl00 access.
- Integral Nodal port for alarm activation of external reporting device.
- Integral computer port supports local printer or IP based management via SLIP/PPP
- On-board NVRAM for non volatile storage of system configuration in the 892x IF card series. In the 893x and 8000-IF series, this technology is moved to the CPU-7, allowing for virtually hitless upgrades
- External synchronization options.
IMACS Interface Cards
The interface cards provide all management and control communications connections to the system and traditionally contained the non-volatile RAM in which all configuration information is stored (NOTE: For CPU-7 based systems, the non-volatile RAM has been moved to the CPU, in order to deliver virtually hitless upgrades). The interface cards provide all communications, control, and network interfaces to the IMACS system. The use of nonvolatile RAM for configuration storage means that all configuration information is retained in case of system power loss or intentional power down. One interface card is required per system.
The control terminal port is used to connect a VT100 or compatible terminal to the IMACS system for node management and control purposes. The Control Terminal port presents an RJ48 female connector with a V24/V28 (RS232) DCE electrical interface. The port is set to VT100 mode for asynchronous operation at 9600 bps with 8 data bits, 1 stop bit, and no parity. The port supports an automatic logout feature after fifteen (15) minutes of inactivity.
The computer port (DB9) connects a local device for printing alarms or can be configured to support SLIP (Serial Line Internet Protocol) for transport of SNMP management information. The computer port presents a DB9 male connector with a V24/V28 (RS232) electrical interface. Note that on the 893x series of cards, this port has been replaced with a RJ45 port.
The function supported by the nodal port is to provide the form-C contact closure and the physical interface so that the ACO alarm may activate an external reporting device. The nodal port presents an RJ48 female connector with an RS485 electrical interface.
The Modem port is used to connect the Interface card’s internal dial modem to a standard telephone line. This port may be used to log into the unit from a remote VT100 terminal or to send system alarms to a remote device. The modem port presents an RJ11 female connector.
The Interface card also provides a single RJ27 50-pin female craft connector on which to terminate all T1/E1 facilities. In the 893x and 8000-IF series of Interface cards used in conjunction with CPU-7 cards, this connector is physically separated from the main card in order to allow for replacement of the intelligent portion of the card while maintaining electrical connectivity to the WAN parts.Download or print data sheet
