ND-70182 (E) CHAPTER 3 Page 279 Revision 4.0 PA-FCHA Fusion Call Control Handler PA-FCHA Fusion Call Control Handler 1. General Function This circuit card is a protocol converter to carry the fusion-link-data from/to the other node. The Fusion- Link-Data is received/transferred from/to the CPR via HUB (PA-M96) across the TCP/IP interface. Once the FCH has received the fusion-link-data from the CPR, the HDLC CONT part of the FCH converts it to the High Level Data Link Controller (HDLC) format, then drops and inserts (D/I) onto a particular channel (or channels) of the ITU-T G.703 digital interface.

Switch setting Standard settings for switches on this circuit card are shown in the table below. LAMP NAME COLOR STATE OPE Green Remains lit while this circuit card is operating. LY RGreen Remains lit while the Fusion link is established. Flash Flashes when the Fusion link test result is fair. (60IPM) OFF Remains off when either the Fusion link is not established or the Fusion link test result is not fair. LBGreen Remains lit while 10-BASE-T port is ready to use. OFF Remains off when 10-BASE-T port is not ready. LOADGreen Remains lit while this circuit card is ready to broadcast data packets. (Forwarding Status) Flash (60 IPM)Remains lit while this circuit card is ready to broadcast data packets. (Blocking Status) Flash (120 IPM)Remains lit while this circuit card is stand-by to broadcast data packets. (Learning Status) OFFRemains off when this circuit card is stand-by to broadcast data packets. (Null Status) EST3 Green Remains lit while sending data. EST2 Green Remains lit when receiving pair cable polarity is normal. EST1 Green Remains lit while receiving data. EST0 Green Remains lit while the link is established. PWALM Red Remains lit when power supply failure (from the BWB) has occurred. SWITCH NAMESWITCH NOSETTINGSTANDARD SETTINGDESCRIPTION MB NoteUP Circuit card Make-busy.

CHAPTER 3 ND-70182 (E) Page 282 Revision 4.0 PA-FCHA Fusion Call Control Handler Note: The following operations are required prior to extracting the card. (1.) Turn on the MNT3 switch. (2.) Flip the MB switch. When the D/I DTI (1.5M) is connected with the card front cable. Note:T203 timer designates the maximum idle time which does not transmit any data frames. As a basic rule, the shorter T203 timer value, the earlier link failure detection will be obtained. MNT0OFF×Not used. 1OFF×Not used. 2OFF×Not used. 3 NoteON Make-busy-request. OFF×Cancel the Make-busy-request. SWITCH NAMESETTINGSTANDARD SETTINGDESCRIPTION MODE0 - 7 Not used. 8×Standard setting. (When the DTI is connected with the card front cable.) 9Fusion link test mode.
