2.2.9 Test Access Mode Definitions
Figure 2-10 MONF Access Dual TAP
Note The MONE and SPLTA modes are applicable to unidirectional circuits from E to F. The MONF and
SPLTB modes are applicable to unidirectional circuits from F to E.
2.2.9.3 MONEF
Monitor EF (MONEF) is a monitor connection provided from the FAD1 (odd pair) to a DFAD, to the A
transmission path and from FAD2 (even pair) of the same DFAD, to the B transmission path of the
accessed circuit. This is a non-intrusive mode (Figure 2-11).
MONEF for T3 (DS3 HCDS) indicates that the odd pair of a FAP is providing a monitor connection to
the A transmission path and from the even pair of a facility access path (FAP) to the B transmission path
of the accessed circuit.

2.2.9.4 SPLTE
Split E (SPLTE) splits both the A and B paths and connects the E side of the accessed circuit to the FAD
(Figure 2-12 and Figure 2-13).
Note QRS is not supported on the ONS 15454, ONS 15327, and ONS 15310-CL. The connection will remain
as is. The ONS 15600 inserts AIS instead of QRS.
