Zhone Technologies, Inc. IMACS Product Book, Version 4 Server Buses The Server buses are all the buses that are accessible by the Server cards. Effectively this is the union of User buses and WAN bases. This enables the Server cards to provide a data processing function for WAN and User cards. The Server/Server card typically provides a centralized processing function on data initially entering the system from User or WAN connections.
Zhone Technologies, Inc. IMACS Product Book, Version 4 Voice Card The IMACS supports a wide-variety of cards to support voice channel bank applications. Typically they are a family of cards each of which provides 8 ports, which translate the analog signal to PCM and translate the signaling information from the analog interface for transmission over a digital facility. The interfaces supported include FXS, FXO, E&M, FXS Coin, FXO Coin and P-phone.
Zhone Technologies, Inc. IMACS Product Book, Version 4 CPU Card Redundancy The IMACS CPU cards typically support redundant operation when paired with an identical CPU card. The CPUs communicate with each other once every second. If there is a problem with the standby CPU (i.e., communications transfer did not take place), an alarm is raised by the active CPU, indicating a problem with the standby CPU. The active CPU monitoring is achieved via hardwire watchdog timers on the Interface Card.
Zhone Technologies, Inc. IMACS Product Book, Version 4 The system will switch to the backup clock source upon detection of one of the following conditions in the currently active source: • • • • • CGA Red Alarm. CGA Yellow Alarm. Out-Of-Service (OOS) condition. Clock source is placed in loop back mode. Clock source is placed in standby mode.
Zhone Technologies, Inc. IMACS Product Book, Version 4 IMACS Management Via PPP or SLIP IMACS alarms are reported either to a local device or via an internal 2400 bps modem in a proprietary ASCII format to a central site. Additionally, the IMACS can be optioned to use TCP/IP and encode alarms as standard SNMP traps. One method of transmitting TCP/IP management information and SNMP traps is to activate the Serial Line Internet Protocol (SLIP) on the DB-9 port set at 9.6 Kbps.
Zhone Technologies, Inc. IMACS Product Book, Version 4 As shown in Figure 4 the IMACS supports multiple methods of communicating SNMP messages and Telnet terminal sessions between an end node and the network management station. The addition of PPP support allows the IMACS to connect to routers or terminal servers to establish a connectivity path to the network management station. The utilization of PPP is similar to that of SLIP.
Zhone Technologies, Inc. IMACS Product Book, Version 4 IMACS IMACS IMACS FDL over ESF DACS Each FDL is mapped to a separate DS0 NMS T1 IMACS 38.4 kbps SLIP Terminal Server Concentrator Node Figure 5 - IMACS Management Using FDL The management DS0s are connected internally to the B7R card with a limit of eight management DS0s per card. The output of the B7R card is RS-232 at up to 38.4 Kbps using SLIP. This output is fed into a terminal server or a router and transported to a NMS.
Zhone Technologies, Inc. IMACS Product Book, Version 4 To manage the IMACS containing the B7R card, a separate SLIP/PPP connection from the DB9 on the interface card is required. The local IMACS cannot route its own SNMP information to an internal B7R card. For example, if a network has eight remote nodes, two SLIP connections are required at the central site - one for the eight remote IMACS and one for the local IMACS.
Zhone Technologies, Inc. IMACS Product Book, Version 4 a) E & M card with 2713 Hz Loop back – Module# 811760: This feature will provide digital loop back (both audio and signaling) when activated by a 2713 Hz tone of specified level and duration. The requirements are provided by BellCore PUB 42004. When a validated tone is detected the channel should disconnect the user and provide loop back of signals (audio and signaling) received from the network.
