Gateway Hardware Specification February 3, 2000 1. Introduction The purpose of this document is to outline all the requirements necessary for the C & I Meter. The C & I Meter will be the link between the Information Managing Units (IMU), the Commercial and Industrial (C&I) Electric Meter and the head end system. The IMUs will reside on the water and gas meters, which will communicate with the C & I Meter via RF. The C & I Meter may reside on a pole top. There will be two types of C & I Meter Wide Area Network (WAN) interfaces defined within this document, however the WAN interface is not limited to just these two. One will communicate back to the head end via a wireless paging system and the other will communicate via Plain Old Telephone Service (POTS). The C & I Meter will consist of a Power Supply, a Control Module, a Network Communications Interface (NCI), a paging or POTS modem and one or two antennas depending on the type of C & I Meter required. The specifications for these modules are listed in the following sections. Presented below are two diagrams depicting the two types of networks that are possible, using the C & I Meter.

Gateway Hardware Specification February 3, 2000 3. Tamper Switch A tamper switch in the form of a mechanical switch will be provided. The switch will be actuated by the lid on the enclosure. The switch will be in the closed position for as long as the lid is closed on the enclosure. Once the lid is opened the switch will open signaling the processor of a tamper situation. 4. Battery Backup A battery backup is required such that if the C & I Meter detects MAINS power outage, it will signal the head end via the WAN of the outage. The battery will hold long enough to support a connection on either of the two currently supported WAN interfaces, telco and pager. There will also be a charger card associated with the type of battery used. 5.
