Like many other members of this forum, I started my career with ROLM, took the journey thru IBM, and now Siemens. I do not appreciate the Siemens bashing. Most of your negative statements are simply not true. I would love to turn this exchange into something positive - by discussing your HiPath switch problems with you, especially HiPath IP solutions. Not sure how to identify myself, as this forum's rules stated not to provide real names, telephone numbers, email addresses, etc. I am in the Irving Training Center, my initials are JL, so look me up. Each HiPath student is provided a CD/DVD with full documentation, either in HTML or PDF format. In the Hicom days, we would ship a full set of manuals to the customer site with the telecommunications system. This practice was halted because in most cases the manuals just sat in the switchroom forever - unused. Being a self-maintainer of any large, complex telecommunications system is a difficult task. At Siemens, we have vast resources to tap. A self-maintainer is very limited in that department. I admit that when a student completes our HiPath basic training, that student needs OJT to master the switch. Trunking, stations, networking, voicemail, VoIP, switch hardware, diagnostics, installation, upgrades, patching, system parameters, client/server apps, etc - are topics that cannot possibly be mastered in the classroom and lab alone. After attending our core HiPath curriculum, our field engineers typically attend "update" training via Siemens Virtual University (internet). Each Siemens field engineer receives full documentation on CD/DVD quarterly. All Siemens documentation is available to Siemens COM employees online. Self-maintainers can order documentation via the Siemens sales process. I would love to chat more, but I must go refer my students to TAC/BLS and call Germany - NOT!
