Located at the office where I work in Burlington, is one of Russia Telekoms more interesting sites. This site hosts failover services for both Cisco UCM and Asterisk, as well as an additional SSL gateway for VPN enabled IP phones and VPN clients for use with softphones. In addition this site also hosts the IBM RS/6000 Model 44P-170 which is the platform for development of applications for managing Russia Telekom. There is also a connection to a Nortel CS1000M / Option 61C which is used for testing in my day job.
The Cisco 2811 and HP Proliant DL360 G4.
VPN connectivity to this site is provided by a Cisco 2811 router, which also provides T1 PRI trunking to the CS1000M and FXS ports for connection of vintage Soviet made telephones. The HP Proliant DL360 is running VMware ESXi with virtual machines running Cisco Unified Communications Manager and Asterisk to provide failover to remote sites in the event the main site in Swanton is disrupted. In the near future I also plan to deploy an additional Avaya UCM server to provide georedundant Signaling Server functionality as well as georedundant NRS.
The IBM RS/6000 44P-170
Located in the machine room with the rack containing the router and server is the RS/6000. The system is headless, lacking a video adapter and solely relying on RS232 for I/O. Located next to the RS/6000 is an Okidata MicroLine 520, attached to an HP JetDirect print server, allowing hosts from all around the Russia Telekom network to submit jobs.

The RS/6000 will be used as a platform to host applications and services used to manage subscribers and monitor the Russia Telekom network.
The CS1000M/Option 61C, big iron.
In my office stands an Option 61C/CS1000M running Succession 3.0 software. This system is tied into Russia Telekom with a T1 PRI trunk. It is equipped with a large number of digital and analog ports, as well as a single node Meridian Mail system. This is perhaps my favorite piece of Nortel equipment in the network, as it really is an engineering masterpiece. Unfortunately due to its appetite for AC current, the 61C is only on during certain times.
The IBM 3151 terminal at my desk.
My desk is sort of a showcase of Nortel and IBM gear of various vintages. The IBM 3151 terminal is my main means of interface with the RS/6000, my Debian hosts in Swanton as well as the primary TTY access to the Option 61C. It’s equipped with a very nice buckling spring Model M keyboard and a pleasant amber display. Behind the terminal is a Nortel M2250 console which is attached to another system we use for testing, a smaller Option 11C that is powered 24/7.
Console for a Pskov-1 (ПСКОВ-1) electromechanical PBX manufactured in the USSR in 1981.
The Pskov-1 console was an interesting eBay find a while back, that I converted into a single line analog set. There will be more on this set in a separate article soon.
RIF-1151 Telephone Concentrator, Made in USSR 1991.
My second eBay find as far as the vintage Soviet telephony gear is a sort of “mini-PBX”. Its a 2 line telephone console, with 8 subscriber ports for attachment of additional phones without dials. These phones can be rang from the console, or lifted to generate a signal on the console. Right now the phone is out of service, waiting on the replacement of around 50 dried out electrolytic capacitors.
ACD answering position.
Also located in Burlington is one of the ACD answering positions that are used to manage incoming calls to the Russia Telekom support and business office DIDs. Incoming calls are placed in queue and treated to music and information RAN (recorded announcement) messages giving information on wait times. The ACD sets can view information on callers in the queue like number of callers waiting and the longest wait time.
