 The New York City Department of Mental Health had a 16 MB Token Ring IBM Type 1 network that had been installed back when DOS applications required little bandwidth and the token-ring network had more than enough capacity to get the job done. The network spanned twelve floors of NYCDMH’s downtown office at 93 Worth Street. Over time, increasingly bandwidth-intensive GUI applications began to outpace the agency’s network capabilities and network performance declined sharply, particularly between users on different floors. Outages increased, productivity dropped, user complaints to MIS Helpdesk became more frequent, and pressure from management to improve was incessant. The agency had Cat 5 cable installed on a piecemeal basis using various vendors.
Solution
EIA engineered and installed fiber optic cabling within inner duct, inside heavy gauge steel BX Conduit connecting the switches on each floor. The project was completed on time and within budget. The next phase called upon EIA to test all the non-standard cable and repair Category 5 cable that had been installed by another vendor.
This required testing re-pulling, repairing, certifying and documenting all the horizontal cable pulls on each floor, to over 425 users.
EIA was able to update its plans and keep in step with moves and relocations that occurred while the upgrades and replacement work was being done. EIA completed all work within the four-week period allotted to the project and without cost overruns.
Result
The Department of Health is recognizing many benefits from this new premise cabling system, including:
- Faster throughput
- A 90% reduction in downtime
- Reduced maintenance costs
- Increased productivity
- User complaints nearly eliminated
