Peripheral Boards
Network interfaces
The TS2 board is connected to the network transfer point (NT1) via the symmetrical line (120
ohms, four-wire twisted-pair cable) at X2 or via an MW line at X5.
Note: use the connection kits listed on Page 3-334 for NT connections in Spain and Portugal.
●
Symmetrical line (120 ohms)
The maximum cable length (approx. 130 m) depends on the quality of the cable used and
its signal attenuation. Use shielded cables only to guarantee proper operation.
Connect the cable to the X2 using an 8-pin Wieland terminal (TS2 only).
●
MW line (MW8 jack (RJ48C))
The shielded 8-pin MW8 (RJ48C) jack X5 is provided for connecting MW lines. The maxi-
mum cable length (approx. 100 m) depends on the quality of the cable used and its signal
attenuation.
