Interface Trunk Units
BRT(4)-U13
ETU
This Basic Rate Interface unit provides
four circuits (eight voice channels) for
ISDN Basic Rate Interface, complying to
the ETSI standard.
The maximum quantity allowed depends
on whether a PRT(1)-U13 ETU, COI( )-
U13 ETU, COID( )-U13 ETU, DID(4)-U13
ETU and/or TLI(2)-U13 ETU are installed.
These units share the total number of
trunk lines.

IPT(4)-U13
ETU This IP Gateway ETU is an optional
Interface that can combine various trunk
and Tie Line calls into Gateway trunks.
This ETU can be assigned as a two-port
TLI(2)-U13 or four-port DID(4)/COI(4)/
COID(4)-U13 ETU.
This ETU can be installed in KSU slots
that support the applicable assigned ETU.
