The T1 Extended Superframe ( ESF ) Format ( a 24 bit code composed of 6 framing bits, 6 CRC Error Checking Bits and 12 Signaling Bits ) was introduced with the D5 Channel Bank, a true 24-channel channel bank chassis, which could also be software optioned to use the Superframe framing format.

In telecommunications, an extended superframe ( ESF ) is a T1 framing standard, sometimes called D5 framing because it was first used in the D5 channel bank, invented in the 1980s.

T1 SF framed circuits yield two independent signaling channels ( A & B ) T1 ESF framed circuits four signaling frames in a twenty four frame extended frame format that yield four independent signaling channels ( A, B, C, and D ).

For example, for E1 trunks the CAS signaling bits are updated once per multiframe of 16 frames ( every 2 milliseconds ) while for T1 ESF trunks the superframe is 24 frames ( 3 milliseconds ).

SF Signaling was the method of Inband circuit control before the advent of the Extended Superframe ( ESF ) framing format.

Two types of framing schemes are Super Frame ( SF ) and Extended Super Frame ( ESF ).

These two types of framing ( SF, and ESF ) use their 8 kbit / s framing channel in different ways.

In June 2008, ESF in collaboration with EUROHORCs ( European Heads of Research Councils ) published a policy briefing ‘ The EUROHORCs and ESF Vision on a Globally Competitive ERA and their Road Map for Actions to Help Build it ’, detailing essential requirements to build a globally competitive European Research Area within the next five to ten years.

These requirements are complemented by a Road Map which outlines concrete actions for EUROHORCs, ESF member organisations and partners.
