Off Peak rates are discounted rates designed to encourage the use of a service provider's communications services at a time which is convenient to them - their off-peak traffic times. Off Peak times are generally night-times and weekends. See also Economy Rates.
- OPX - Off Premises Extension
- An extension which is located remotely from a PABX. OPX was an expensive service offered by service providers and was little used in the past. OPX is gaining great interest with the introduction of IP telephony and VoIP. OPX allows secondary office phones (and employees at home) to use their handset as though they are connected to the PABX. Extension dialling, call transfers, etc. become available with OPX.
- One-way Satellite
- Internet connection using a satellite download link and a landline for the upload link. Often used in conjunction with the an ISDN2 connection to provide a 64Kbps or 128Kbps upload link. This connection has generally become superseded in regional areas, with the introduction of the Two-way Satellite connections (offering 256Kbps uploads, for example, without the monthly connection costs).
- Online Access Centres
- Public areas which provide user Internet access, with user equipment supplied. Libraries are a good example of an Online Access Centre.

- Override Codes
- Each Australian service provider has its own four digit override code. Calls to domestic or international destinations may be made through a provider by dialling their code before the required number. Override codes may be used on a call-by-call basis. (The user should also have an account with that provider, otherwise the call may be blocked.) Pre-programming a PABX to use override codes for certain call types is one form of LCR (Least Cost Routing).
