AFCD: Assignment of Fixed Connection-Nailed Down Connection-Data
1. General
This command is used to assign (connect link), delete (release link), and display the data (linked LENS) per-
taining to Fixed Connections (Nailed Down Connections).
2. Precautions
1. The Nailed Down connection available among the following circuit cards/terminals.
Single Line station (Line circuit)
D
term
(ELC)
Trunk (DTI, etc.)
Conference Trunk (CFT)
Digital Signaling Trunk (DST)
MODEM Trunk (MDMT)
Data Module (DTL)
Netfusing Call Control Handler (FCH/FGH)
2. The status of the link is supervised periodically by the system. If the link is not in a “Nailed Down Con-
nection”, the link will be forcibly released and reconnected.
3. The port specified by the LENS-A parameter and LENS-B parameter are “Nailed Down”, with respect to
the EAD-A parameter and EAD-B parameter.
4. The EAD-A parameter and EAD-B parameter should be entered by the hexadecimal value as explained in
Table 4-19.
Table 4-19 Data for EAD-A/EAD-B
Note 1: When DTI is used for Data Communication, Pad Data must be “7” (binary 111).
Note 2: When bit stealing (signaling bit) is used in DTI, signaling bit (CD RS bit) is lost.
0/1 = -/To inhibit stealing bit (signaling bit) per channel in DTI
