Getting Connected
Once the studio codec is configured you are now ready to receive an incoming call from the remote
codec over the internet. Always dial from the field codec to the studio codec over the internet unless
the remote codec is assigned a public static IP address and you know this address. If you dial the
studio using a cell-phone data network at the remote site you will not normally experience any
firewall or port blocking issues at the remote end of the link using default Tieline ports.
Troubleshooting: How to Determine Where Firewall Port Blocking is
Occurring
If you find you are unable to either send or receive audio between the studio and remote codecs you
can use Tieline's Link Quality reading to diagnose where ports are being blocked. LQ can be
displayed on the front
LCD SCREEN of Tieline's Bridge-IT, Merlin and Genie codecs by selecting
Cxns , then select the connection you want to view and press the OK button. LQ readings are also
displayed on the home screen of all Commander and i-Mix G3 codecs.
Link Quality (LQ) Readings
Send and Return LQ numbers help you to determine if a problem is occurring at either end of a
connection. For example, on an IP connection the Return LQ reading represents the audio being
downloaded from the network locally (i.e. audio data is being sent by the remote codec).
Conversely, the Send LQ reading represents the audio data being sent by the local codec (i.e.
being downloaded by the remote codec). To ensure a stable connection, try to maintain a
reliable reading of 80 or higher for both the
Send and Return LQ reading.
Important Note:
· The Return link quality reading is the same as the Local ( L ) setting displayed on a
G3 codec.
· The Send link quality reading is the same as the Remote ( R ) setting displayed on a
G3 codec.
Diagnosing Port Blocking via the Studio Codec LQ
If the studio codec Return LQ reading is 01 then incoming audio from the remote codec is being
blocked by a firewall at either point A or B in the following diagram. If the studio codec Send LQ
reading is 01 then outgoing audio from the studio is being blocked by a firewall at either point C
or D in the following diagram.
