496 B34 Codec Static Loss Plan Downloading
equivalent to pad out is switched in. For XDID, XFCOT, and XFEM trunks,
the base level (static) value is switched in when connected to the DTI2
trunk types.
GEC Plessy hardware
No losses are sent to XCOT, XDID, and XFEM trunk cards when these
cards are connected to GEC hardware, since there is no dynamic switching
done for them. On the GEC hardware side of such a connection, the pads
are switched in according to the type of trunk (near end) as opposed to
what it is connected (far end); therefore, the loss is switched in regardless
of whether the connection is to XCOT, XDID, and XFEM trunk cards or
other types of cards.
Intelligent Peripheral Equipment Completion
Whenever a TIE/LDR trunk is configured on an XIDID card, for Static
Loss Plan Download (SLPD)/Dynamic Loss Switching (DLS), loss/level
is downloaded/switched to an XDID card with the type 12 message.
Depending on the Class of Service configured, Non-Transmission
Compensated (NTC), Transmission Compensated (TRC), or Via Net Loss
(VNL), the TIE unit will be mapped to the following B34 port types: B34
T2WN, B34 T2WT, or B34 T2WV.
ISDN Basic Rate Interface
It is possible to switch in loss on the ISDN BRI side, based on port types.
MFE/MFC Pads
The Alternative Loss Plan feature allows trunks to be configured so as to
have pads switched in when an MFS sender/receiver is equipped. For such
a configuration, the following occurs for B34 port types:
• Pads are switched in for outgoing calls (the trunk is the originator).
• Pads are switched in, if in the dialing state, for incoming calls (the trunk
is the terminator).
Feature packaging
B34 Codec Static Loss Plan Downloading requires Intelligent Peripheral
Equipment (XPE) package 203.
