8/16 E1/T1 Ports Supported. E1 ports impendence are E1-120

 for twisted 

pair cables or 75

 for coax. The E1-120

 RJ45 sockets are default for ports. 

The E1-120

 connection cable is made with RJ45 connectors and a length of 

4-pair twisted cable. The cable is not provided with the equipment, and the user is 
responsible for making such cables in the field with length suitable for a particular 
installation. The signal definition is given in Table 3.2.2-1, and pin order is depicted 
in Fig. 3.2.2-1. Note that pin-1 and pin-2 should use the same twisted pair, so should 
pin-4 and pin-5.   
E1/T1 service can set the actual service quantity by NMS, set the exact E1 E1/T1 
channels received by local equipment from remote equipment, realizing E1/T1 
service one point to multi-point unidirectional transmission function.   

By NMS, E1ports provide local loop back and remote loop back, 8 E1 ports loop 
back can be set independently, and by the dip RA on front panel E1 indicators can 
be controlled to indicate local or remote ports LOS and AIS status. The local and 
remote loop back definition is shown as Fig 3.2.2-3:

circuit including H0FL-ETHMUX V16 in the two endss and the link between them.   

3.2.3

 

Ethernet/optic fiber connection 

H0FL-ETHMUX V16 provides 5 standard RJ45 Ethernet interface and a LC optical 
interface for connection with the transmission network, such as wireless Ethernet 
bridge interface; or access to a local Ethernet port, such as switch and so on. Any 
Ethernet electrical interfaces can be used for Web Server or SNMP management and 
device software and hardware upgrades.   
Ethernet Optical adopts SFP integrated optical modules, marked with 

Æ

 for the 

optical signal input. marked with 

Å

  for the optical signal output. Optic fiber 

access though patch cord. Connect the plug socket when the optical module should 
be made to plug into the socket pin on the positioning of the corresponding gaps, 
and plug in place. Patch cord bending radius is no less than 50mm. Plug optical 
connector, not directly pulling fiber. Please keep the socket on the SFP protection 
plug, no plug inserted optical fiber, be sure to protect plugs, prevent dust entering.   
  

 

Note: 1. This equipment Ethernet electrical interface with the HP auto-MDIX 

feature that automatically detect network cable transmitting/receiving sequence and 
then adapting, both of MDI and MDI-X Ethernet interface, both crossover cable or 
straight cable can be used.
