1.2.2 IVD Master Overview
The purpose of 19" modularized master unit is as a central unit in stacking application to manage
all slave units connected with it. Master unit always collects related information from slave units.
Moreover, users can manage slave units through master unit.
The system can operate individually covered modular built-up system.
The picture of master unit is shown in Figure 1-3.
Master unit supports some features are as following –
Network Interface - The trunk should be 1000-Based LX, SX or GE Interface.
‧ 1000 Base T; according to IEEE 802.3-2002
‧ 1000 Base SX; according to IEEE 802.3-2002
‧ 1000 Base LX; according to IEEE 802.3-2002
Cascade Interface - GE interfaces can be cascaded up to six IVD slave units.
The Ethernet interface (full-duplex) throughput provides 100 Mbps (Fast Ethernet) or min. 500M
for GE interface
Capacity – It supports subtended 6 slaves with ADSL 2/+ port range from 24 to 144 ports.
Security – It supports Packet filter, and password protection.
Redundancy – Optional uplink automatically switch of activity in the event of fiber failure.
Inventory Savings - Common equipment across central office and outside plant deployments.
Management - Single IP Management.
Q.o.S - Packet filter and classification.
Dimension (HxWxD)- 44.45mm (1.73 in) x 440mm (17.32 in.) x280mm (11.02 in.)
