Failure to use a shielded cable may negate your regulatory approval. |
The T1/E1 network cable requirements vary based on the CG 6565E interface. The following table summarizes the network cabling for the CG 6565E board:
|
Interface |
T1/E1 120 ohm cabling |
E1 75 ohm cabling |
|
Dialogic® MD1 Mini RJ-21 (up to 8 trunks) |
Dialogic® MD1 Mini RJ-21 to Dialogic® MD1 RJ-21 cable connected to a signal entry panel or punchdown block. |
Configure as E1 120 ohm. Connect a shielded 50-pin Telco cable to a signal entry panel or punchdown block. Connect the signal entry panel or punchdown block to a balun panel or equivalent to convert the impedance from 120 to 75 ohm. |
|
Dialogic® MD1 RJ-45 (up to 4 trunks) |
Dual T1/E1 120 ohm adapter cable connected to a shielded RJ-48 cable (or equivalent). |
Configure as E1 75 ohm and use an Dialogic® MD1 RJ-45 to two 75 ohm BNC adapters cable. |
