Page 9: Installation
2 - INSTALLATION 2.1 System Architecture The Model 9525AY can be configured into three basic network architectures with almost unlimited variations. Typically the rack mountable Model 9521Y is used at the central hub. The standalone Model 9525AYs are used at the remote (local) locations. However, either modem can be used in either installation if so desired. - Page 10 3 – M IGURE ULTIPLE AISY HAIN RUNKS WITH ASTER ONTROLLER...
- Page 11 The same cable and the Model 9525AY may be installed into the expansion port of any modem along the trunk in order to establish a single or double branch from that trunk. Additional branches can be made off of these branches, etc., without limit. NOTE: IN ALL THESE INSTALLATIONS, THE TX1/RX1 PORT WILL BE CONNECTED TO THE FIBER GOING UPSTREAM TO THE CONTROLLER AND THE TX2/RX2 PORT WILL BE CONNECTED TO THE FIBER GOING TOWARDS THE FAR END OF THE TRUNKS OR BRANCHES.

Page 13: Modes Of Operation
2.1.3 Fault Tolerant Redundant Ring With the architecture of Figure 4, all modems are arranged along a dual fiber ring, starting with the master controller modem (operating in Master Fault Tolerant mode), looping through an indeterminate number of local terminal modems (operating in Local Fault Tolerant mode), and terminating back into the second set of optical ports of the master controller modem, completing the ring. - Page 14 5 – I IGURE NTERNAL IGNAL OUTING FOR 2.2.2 Local Daisy Chain Mode In this mode, there is a specific "upstream" and "downstream" data direction, because data is only transmitted to or from the master and not both directions on a ring. Specifically, the TX1/RX1 port communicates upstream to the master controller and the TX2/RX2 port communicates downstream to the next modem on the daisy chain.

Page 15: Operational Features And Considerations
2.2.3 Master Fault Tolerant Mode This mode is virtually the same as the master daisy chain mode explained in Section 2.2 with these exceptions: Because this is a fault tolerant mode, data will normally be received via both optical ports, skewed slightly in time of arrival. - Page 16 2.3.2 Optical Side Anti-streaming The optical side anti-streaming feature, when enabled, disconnects an optical receiver from the circuit in the event that the receiver's output goes high for a period longer than would be expected in normal data flow. This may occur due to a receiver failure, a transmitter or terminal equipment failure, or if the receiver input is left open to strong ambient light (850 nm versions only).
- Page 17 prevented from seizing the priority. This feature will allow guaranteed priority for the shortest transmission path around the ring as long as the propagation time around the ring is less than 12 ms. This is equivalent to a ring 500 km long with 500 repeating modems in the path. In the event of a failure of the data path with has current priority, a wait of at least 12 ms must occur before the other transmission path is selected.

Page 18: Set-Up Procedures
2.4 Set-Up Procedures The Model 9525AY has an 8-position and a 10-position dipswitch accessible via the rear panel. Program each of these switches upon installation as required for your chosen network configuration and feature set. Note that all optional operational features controlled by the TIMEOUT dipswitch are disabled when switches 1 through 6 are in the down position. -

Table 3 – Mode and Interface Select Switches 2.5 Mounting 2.5.1 Standalone Mounting The model 9525AY can be mounted directly to a flat surface using the attached mounting plate. The mounting plate attaches to the bottom of the unit using four screws. Use the oval holes in the plate to mount the unit to the flat surface. -

ST OPTICAL CONNECTION Align the key and the bayonet slots on the ST connector with the keyway and the bayonets of the ST optical port. Slide the connector ferrule into the port until the key and bayonets are engaged. Push the coupling nut forward until it can be turned clockwise to lock the connector into the port. - Page 22 Table 4 – RS232 Pinouts on DB25S Connector Pin # Identification Input/Output to modem and auxiliary information.
