2. New Board Description CLCOB4/8 Description Switching Functions CLCOB4 provides 4 Loop start CO line interface. CLCOB8 provides 8 Loop start CO line interface. CLCOB4/8 can be installed on the universal slot No.1-9 of any KSU. Maximum 200 analog lines limit Analog CO interface ports. Pulse Dial function is not applicable in CLCOB8. CLCOB4/8 are implemented to accommodate CIDU4/8 option board. Add-on boards : -.CLCOB4 : DTRU4, CPTU4-C, CIDU4(CID + CMU-50PR) -.CLCOB8 : DTRU4, CPTU4-C, CIDU8(CIDU + CMU-50PR) Switching Functions LED Indications-CLCOB4/8 Let’s see CLCOB board. The operation of CLCOB is the same with the existing LCOB board. The difference from the existing LCOB is that CLCOB can detect CLI signal sent from PSTN. The function can be enabled by inserting CIDU optional boards. We will explain CIDU next page. (Move to next page) 7/16

2. New Board Description CIDU4/8 Description Switching Function There are two types of CIDU4/8, FSK-CIDU4/8 and DTMF-CIDU4/8. FSK/DTMF CIDU4/8 detects Caller ID signal that are supplied from the CO line interface. FSK/DTMF CIDU4/8 interface contains Microprocessor, CID Unit in the Memory, Call Metering Unit (CMU-50PR). FSK/DTMF CIDU4/8 is used as an Option Board in CLCOB4/8 and cannot be used alone. Only when CIDU4/8 is inserted to CLOB4/8, the MPB recognizes CLOB4/8 board as IPP board. FSK-CIDU4/8 enables CID function in case of On-hook(Type I) and Off-hook(Type II). DTMF-CIDU4/8 enables only for On-hook(Type I). Switching Function LED Indications Let’s see CIDU optional board.

Its main job is to provide the Ethernet interface for S/W applications and VOIP feature with optional VOIUE daughter. VOIB is installed on the universal slot No. 1-9 of KSU except the slot No. 9 of 1st KSU. The number of ports are expanded to 24 channel comparing with the existing VOIB. VOIBE has twelve(12) ports basically and VOIUE has additional twelve(12) ports. Switching Functions LED Indications Let’s see VOIBE board. The operation of VOIBE is the same with the existing VOIB board. The difference from the existing VOIB is that the number of ports are expanded to 24.
