NT and TE defines the response for the MODE prompt in Overlay 27.
Note 4
In-circuit protection against power line crosses or lightning is not provided on the SILC card.
When the SILC line card is used in TIE trunk applications in which the cabling is exposed to
the outside plant conditions, an NT1 module certified for such applications must be used.
Check local regulations before providing such service.

ISDN BRI QSIG connectivity

The European Computer Manufacturer's Association (ECMA) has defined an
ISDN protocol that specifies the Layer 3 signaling requirement for support of
circuit switched call control at the "Q" reference point between Private
Telecommunications Network Exchanges (PTNXs) connected within a
Private Telecommunications Network (PTN). This protocol has been adopted
by the European Telecommunications Standards Institute (ETSI) and the
International Standards Institute (ISO). Most of the major European PTNX
manufacturers will be supporting ISDN BRI (as well as ISDN PRI)
connectivity based on the ISDN QSIG (ETSI and ISO) standard.
