3GPP44.006Data Link (DL) layer specificationMobile Station - Base Station System (MS - BSS) interfaceRelease 17TS
G.4.1 EL bit error
If the EL bit is set to "0", an MDL‑ERROR‑INDICATION primitive with cause "frame not implemented" is sent to the mobile management entity.
G.4.2 Information frames
If the length indicator of an I frame is set to a numerical value L>N201 or L=0, an MDL‑ERROR‑INDICATION primitive with cause "I frame with incorrect length" is sent to the mobile management entity.
If the numerical value of L is L<N201 and the M bit is set to "1", then an MDL‑ERROR‑INDICATION primitive with cause "I frame with incorrect use of M bit" is sent to the mobile management entity.
G.4.3 Supervisory frames
If a supervisory frame is received with L>0 or with the M bit set to "1", an MDL‑ERROR‑INDICATION primitive with cause "S frame with incorrect parameters" is sent to the mobile management entity.
G.4.4 DISC and DM frames
If a DISC or DM frame is received with L>0 or with the M bit set to "1", an MDL‑ERROR‑INDICATION primitive with cause "U frame with incorrect parameters" is sent to the mobile management entity.
G.4.5 SABM UA and UI frames
If SABM, UA or UI frames are received with L>N201 or with the M bit set to "1" an MDL‑ERROR‑INDICATION primitive with cause "U frame with incorrect parameters" is sent to the mobile management entity.
