The ADM shall be installed in designated enclosures as shown on the plans, as detailed in the Special Specifications, and as directed by the Engineer. 2. Material. A. General Requirements. All materials furnished, assembled, fabricated or installed under this Item shall be new, corrosion resistant and in strict accordance with the details shown on the plans and in the specifications. The ADM shall be fully compatible to the existing ADMs installed on the field and at TransVista Traffic Management Center. B. Functional Requirements. The ADM shall operate with optical data streams of OC-12 Functionality optical transmission system. The ADM shall be of modular design consisting of a 19" rack mounted shelf unit with front access only plug-in modules. The ADM shall be designed to create a network topology consisting of a dual counter rotating fiber optic ring with two fiber strands. The ADM shall use an industry standard based Time Division Multiplex (TDM) frame method as deployed in ADM and equivalent systems. ADM shall provide redundancy for the fiber optic interface, power supplies and multiplex controller cards. The ADM system shall be capable of interfacing to lower bandwidth systems. The ADM shall, as a minimum, have the capability to interface T1, E1, 64Kb/s CCITT, RS232, RS422, RS485, Ethernet 10/100 mbps, full motion video, and voice by plugging modules into a single ADM shelf. The ADM system shall be upgradeable to the highest, 2.5 gbps (OC-48), without interface card or chassis changes/modifications. All interface and services shall be input at their native level/protocol and output similarly. The ADM shall be designed in such a way that asynchronous data channels may be multipoint drop and add functions. The network shall allow the end user to set up point-to-point links between users but also broadcast, multipoint and multi-drop connections. The device shall be capable of receiving selected data channels from any location (drop) and of transmitting selected data channels back to any location (add). Multi-drop connections allow a master device to send information to various slave devices. The slave stations shall be able to send a response back on request of the master. In a multipoint data channel, multiple asynchronous data ports may share the same bandwidth on the network such that communications from the control center is dropped at all field locations. Each ADM shall have the plug-in provisions, including connectors, for data and voice assignments as shown on the plans

2 All ADMs shall be connected to the fiber optic cable via fiber optic ports residing on the ADM control modules. Each ADM shall have two optic modules each with transmit and receive fiber optic ports. The entire network will utilize 4 fiber optic strands to create a ring configuration (2-in; 2-out) that will be protected from power failure or ADM failure at any single location. The ADM shall have the capability to operate in fold back mode so that if power fails at one location the ADM on each side of that location will fold back the signal on the fiber optic cable and continue to operate with full capacity. Transition time to and from fold back mode shall not exceed 150 msec. The ADM system shall be capable of adding or removing ADM units without service disruption or downtime. The equipment interface modules shall be hot swappable, so that they can be replaced without interrupting network traffic. The configuration of deployed modules should be available in a database so new modules can be configured with minimal downtime. 1. All equipment interfaces shall be in the front of the node, rear access shall not be allowed. All voice, data, LAN and video interface cards, system chassis and power supplies shall operate on all systems, independent of system control and optics cards. In this manner the investment of interface cards can be maintained while increasing the bandwidth of the ADM. External housekeeping alarms must also be accommodated via each of the controller cards.
