A "Community Dial Office" (CDO) was a small Class 5 telephone exchange in a rural area.

These most often provided capacity for 1,000 or fewer customers and were designed for unattended operation. CDOs could be step by step, all relay or crossbar. Many offices provided four-digit local dialling to small rural communities where a call outside the local exchange was long distance.

Initial deployments were based on step-by-step equipment such as the Western Electric 350A (first deployed on May 27, 1928, in Arcadia, California) and its successor models 360A, 355A and 356A. These switches had some design similarities to No. 1 step-by-step systems already in use in large offices (10,000 subscribers or more) but were of a simpler design (line finders would only need to scan hundreds of lines instead of the thousands in use in the cities) and not designed for expandability.

Any operator assistance or toll call billing for these unattended stations was handled remotely at a larger exchange in the city.

In the 1960s, Northern Electric developed the SA-1 community dial office as a small Class 5 crossbar switch for local use in rural areas.

In the late 1970s, Western Electric's number 3 Electronic Switching System (ESS) was installed in small communities with up to 4,500 telephone lines; it also served as workhorse in some large private branch exchange installations.

Late in the 20th century the smallest offices were replaced by remote concentrators connected to a host office in an adjacent exchange area, which may be several miles away. Others were replaced with distributed switching hardware (a remote switching centre controlled by a digital switch in the city) or with small digital switches such as Nortel's DMS-10 (a self-contained exchange for up to 8,000 subscribers).

OTP is a collection of useful middleware, libraries, and tools written in the Erlang programming language. It is an integral part of the open-source distribution of Erlang. The name OTP was originally an acronym for Open Telecom Platform, which was a branding attempt before Ericsson released Erlang/OTP as open source. However neither Erlang nor OTP is specific to telecom applications.

The OTP distribution is supported and maintained by the OTP product unit at Ericsson, who released Erlang/OTP as open-source in the late 90s, to ensure its independence from a single vendor and to increase awareness of the language.

The Satellite Launch Vehicle or SLV was a small-lift launch vehicle project started in the early 1970s by the Indian Space Research Organisation to develop the technology needed to launch satellites. SLV was intended to reach a height of 400 kilometres (250 mi) and carry a payload of 40 kg (88 lb). The first experimental flight of SLV-3, in August 1979, was a failure. The first successful launch took place on 18 July, 1980.

It was a four-stage rocket with all solid-propellant motors.

The first launch of the SLV took place in Sriharikota on 10 August 1979. The fourth and final launch of the SLV took place on 17 April 1983.

It has taken approximately seven years to realise the vehicle from start. The solid motor case for first and second stage are fabricated from 15 CDV6 steel sheets and third and fourth stages from fibre reinforced plastic.
