Analogue Lines (PSTN)

These are your basic lines.  They are most commonly used as a phone or fax line and to give broadband access. (Broadband can only be installed on a single analogue line)

The minimum lead time for installing a new single analogue line is 5 working days.

ISDN2 Lines (BRI)

A basic rate ISDN line provides two ‘channels’, each of which can be used for separate calls, thus equivalent to having two regular lines. ISDN2 is provided in pairs each of which is described as a circuit.  ISDN2 is traditionally used where a client requires digital lines but not require more than 8 channels.

ISDN allows numerous features that are not available on analogue lines.  These include Direct Dial numbers (DDIs), Trunk to Trunk calls, Caller Line Identity Presentation (CLIP).  ISDN2 lines can also carry data and are sometimes used for CCTV and other data circuits.

ISDN30 Lines (PRI)

ISDN30 or primary rate as it is sometimes called is delivered via a bearer as opposed to multiple circuit boxes.  The bearer allows for a minimum of 8 channels and a maximum of 30 channels, although you can have multiple bearers on one number. 

Most of the same features that are available on ISDN2 are available on ISDN30, but the key benefit of ISDN30 is that the set-up costs become much cheaper per channel as the volumes increase.  ISDN 30 also allows a customer to increase line capacity one line at a time, whereas ISDN2 must go up in pairs.

SIP Trunks

A Session Initiation Protocol (SIP) connection is a Voice over Internet Protocol (VoIP) service that connects a company’s private branch exchange (PBX) telephone system to the public switched telephone network (PSTN) via the Internet.

Using a SIP connection may simplify administration for the organization as the SIP connection typically uses the same Internet access that is used for data. This often removes the need to install Basic Rate Interface (BRI) or Primary Rate Interface (PRI) telephone circuits.  SIP trunks are also significantly cheaper than ISDN channels.

Transferring to ECL Telecom is seamless, with no loss or interruption of service.
