The u17 is the first one, thenu18 is above it at 80000.

Superuser password is "Superuser", debug may be "God". From the main screen you can go into "sYs" and then "Reg" to reset the system.

Cards

DSM-II

Part Number: PRM-816460 Marking: DSM 4W 4SS

Digital Simulcast Modem 2. This is the card where the magic for analog happens in. This card time-stamps the audio at input using the 1pps GPS input. At the other end of the network it can buffer it and release it after enough delay which exceeds the worst case transport system delay. Should the delay vary, the card will take care of this using the buffer so long as the delay is less than the buffer size.

This supports broadcast and non-broadcast mode. In the broadcast mode, the SDA is not used, The distribution function is performed in the channel bank at the WAN level.

Non-broadcast mode is the simplest mode to understand. The DSM ports are a 1:1 mapping from the prime site to the remote sites. They are a book-ended audio transport.

Broadcast mode is more complex, only one DSM port is the prime port. The TX audio (from USCI/CSCI) is injected here, and it is digitally replicated to the remote sites. The other DSM ports are slave ports at the prime sites are used for RX audio only. This configuration is the only supported configuration for securenet and eliminates the need for a SDA

Extended Broadcast mode is used when a prime site must scale > 28 analog links. This allows you to subtend additional channel banks at the prime site.

Non-Broadcast mode - =>v1.3 DSM firmware & Rev A DSM hardware
Broadcast Mode - =>v2.4 DSM firmware, Rev C Hardware, CPU v3.43
Extended Broadcast - =>v2.4 DSM firmware, Rev C Hardware, CPU v4.x
