DRU on SV8500

[phadobas]

I have a 2400ICS and now an SV8500. Many of our users on the 2400 are connected by DRU. I'm experimenting with switching over some of those users from the 2400 to the 8500 by connecting the DRU to the 8500. I have programmed some stations, moved the DRU interface card from the 2400 to the 8500 and connected the DRU to it but the phones on that DRU didn't work. I'm using DRU-s over E1 for 30 Dterm Series e phones. The 2400 was purchased in 1999 with all its DRU-s.
The manual of the SV8500 DOES have a section about using DRU-s, but it doesn't say what firmware do I need to have in the DRU and its interface card. I think that's where the problem coming from: I have old firmware chips on them. Has anybody made these work? Am I correct in assuming that I need new firmware in them?

This should give you the information you need. It lists the tpye, circuit card, sp chip set number, etc.

Thank you. I requested pricing on this from my vendor.

Just to circle back on this, the chip upgrade DID make the DRU work. Thanks for the advice.
