Note1: For the Ethernet and E1 card, Hot plug is not supported!

Note2: Before hot plugging the SFP optical module, both the operator and the device must be connected to the same earth in a reliable way! Otherwise, the device may be damaged!

 

2.4 Introduction to E1/Etherent Card

ARIOO-320 can provide four kinds of E1 card to provide E1 interface: CLIU4, CLIU8, CLIUB4-B and CLIUB8-B E1 card, and provides CET4 card, to provide Ethernet interfaces.

Note: The E1/Ethernet card do not support hot-pluggable, before installing E1/Ethernet cards, make sure the equipment is power off and open the chassis.  

 

2.4.1 CLIU4/8 E1 Card

CLIU4/8 is the unbalanced E1 card providing 4/8 E1 unbalanced interfaces with a bit rate of 2.048 Mb/s, which is compliant to ITU-T G.703 standard. It adopts DB37 connector as its physical interface, provides BNC interfaces by DB37F-BNC-4/8E1 cable adapter. Refer to Appendix 2 for E1 adapter.

 

2.4.2 CLIUB4/8-B Card

CLIUB4/8-B is the balanced E1 card providing 4/8 E1 balanced interfaces with a bit rate of 2.048 Mb/s, which is compliant to ITU-T G.703 standard. It adopts RJ45 connector as its physical interface. Refer to Appendix 2 for more.

 

2.4.3 CET4 card

CET4 is an Ethernet card used for local LAN access and can provide 4 shared electrical Ethernet interfaces compliant to IEEE 802.3u 100 BASE-TX standards. These 4 Ethernet interfaces share a wan channel, the bandwidth of which can be up to 100Mb/s.

The 4 fast Ethernet interfaces operate in full or half duplex with flow control, besides, CET4 supports VLAN function.

 

 

3 Typical Application

ARIOO-320 can be used to build point-to-point network, the four Ethernet ports share 100Mb/s, as the following figure shows:
