    VT100 or PC or through a network management system using SNMP. The IMACS is a component of a complete line of managed, integrated access solutions from Zhone Technologies. Figure 1 shows how the service provider can deliver a complete suite of fast, efficient and reliable business communication services to the customers by deploying the Sechtor 300, IMACS, the StreamLine and the Z-Plex 10.
  • Page 6 Zhone Technologies, Inc. IMACS Product Book, Version 4 IMACS Features and Benefits Flexibility and Intelligence Global Standards Compliant—ensures product can be integrated in any international telecommunications network. Provisioning for extensive array of services and applications—flexibility which enables providers to generate revenues without replacing existing equipment.
  • Page 7 Zhone Technologies, Inc. IMACS Architecture Overview The IMACS chassis architecture supports three types of buses and five card types. The buses are the: User Server Communicating through the buses are the following five card types: User Server Interface Each system has at least one CPU, WAN and one Interface card. These three cards provide common functions for the shelf.
  • Page 8 Zhone Technologies, Inc. NETWORK MANAGEMENT SNMP AGENT NODE MANAGEMENT MODEM TELNET VT100 RITS EXTERNAL ALARMS VOICE DATA E&M User Buses The User buses are essentially a group of four Time Division Multiplexing (TDM) highways, each 2.048 Mbps in capacity, and named A, B, C, and D. They are utilized by the User cards to format their traffic for further processing either by Server or WAN cards.
  • Page 9 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.
  • Page 10 Zhone Technologies, Inc. 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.
  • Page 11 Zhone Technologies, Inc. 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.
  • Page 12 A typical SNMP management architecture involves a Manager, such as Zhone Technologies’ Element Management System (EMS) product and an SNMP Agent, which is responsible for providing device management data to the manager. Agents come in two forms: Embedded and Proxy. Embedded agents run directly on the device being managed, while Proxy agents require an intermediate system to translate from a proprietary messaging format.
  • Page 13 Zhone Technologies, Inc. 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.

  • Page 14: Frame Relay

    Zhone Technologies, Inc. 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.
  • Page 15 Zhone Technologies, Inc. IMACS FDL over ESF 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.
  • Page 16 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.

When an ATM network is installed, typically there is excess bandwidth and port capacity that behooves such a merger of networks. For instance, when an ATM switch is deployed each line card will have multiple ATM ports out of which only one or two may be used for data traffic.
