• Called number
• Network Class of Service (NCOS)
• Traveling Class of Service (TCOS)

• Queue identification number (for CCBQ)
NSIG operates within the following parameters:
• A Main can connect to only one Node, and both switches must be
equipped with the NSIG feature.
• TIE trunks between Nodes and Mains must be arranged for Dual-tone
Multifrequency (DTMF) sending/receiving and wink-start operation.
• Meridian 1 Node compatibility with Electronic TIE Network (ETN)
switches is limited to seven-digit on-network and ten-digit off-network
calls.
Network Traffic
The Network Traffic (NTRF) feature enables traffic data related to BARS,
NARS, and CDP to be retrieved and output at a traffic TTY. The network
traffic measurements (in addition to the switch traffic measurements) are
described in detail in the Nortel Networks technical publication (NTP),
Traffic Measurement Format and Output guide.
Network Speed Call
Network Speed Call (NSC) enables a user who is normally restricted from
making network calls to make such a call through BARS/NARS, provided
that the destination is a number defined in a System Speed Call (SSC) list.
When such a call is placed, the CLS and TGAR restrictions are lifted and a
Network Class of Service (NCOS), associated with the SSC list, is assigned
for the duration of the call. NSC is described in detail in the Basic and
Network Alternate Route Selection: Description (553-2751-100).
