L’avertissements concernant la sécurité
Quel que soit le matériel qui est raccordé aux port le système doit respecter les exigence de la
norme UL60950-1 au sujet des circuits SELV.
Il conviendra de rechercher l’avis d’un technicien de télécommunications avant l‘installation de
la carte et sa connexion au réseau.
Line Interface
Each network port on the card carries one service connection via a screened twisted pair cable
of 100 ohm characteristic impedance. There is one transmit pair and one receive pair. A T1
service will normally carry 24 channels and a T1-PRI service will carry 23 channels. The card is
designed to connect to an FCC or IC listed Channel Service Unit (FCC, IC or UL Listed CSU),
which is not supplied by Aculab. The default line build out setting is suitable for cables up to
133 feet between the card and the FCC, IC or UL Listed CSU.
Network Cable Pinout
The 8-contact RJ48 (RJ45) Telephone Modular Plug on the cable between the card and the
network must be wired as follows:
Pin
Signal
Function
Direction
4 LTT Transmit
(tip) output
5 LTR Transmit
(ring) output
1 LRT Receive
(tip) input
2 LRR Receive
(ring) input
RJ48 (RJ45) connector
The cable and plug must be shielded types, with ferrite damping ring, to ensure EMC
compliance.
If a cable is to be produced to wire into a network trunk connection, the connector on the
network end of the cable must be wired as appropriate for the network terminating unit or Listed
Channel Service Unit (FCC, IC or UL Listed CSU) provided.
A 'cross-over' cable is required to connect two T1 ports 'back-to-back', for example, when one
port is to run an exchange end emulation and the other port a user end application. The cable
should be wired as follows.
