Speech calls
If the card is used in an application that makes or answers calls with a service code
that indicates a speech or telephony call, or any call that may use a partly analogue
route, there is a requirement that audio signals transmitted are encoded using G.711
μ
-law PCM.
Many of the speech and FAX resource cards that may be used with the card comply
with this requirement. It is the responsibility of the user to ensure that this requirement
is complied with, by confirmation via the manufacturer of the card, or by any other
suitable means such as independent testing.
Signal sources that do not in themselves guarantee compliance with this requirement
must be conditioned by appropriate circuitry before transmission.
Card installation & connection
Safety warnings
Interconnection circuits should be such that the equipment continues to comply with
the requirements of CSA C22 for SELV circuits, after making connections between
circuits using any of the electrical interfaces.
Refer to a competent telecommunications engineer before installation and connection
to a network.
L’avertissements concernant la sécurité
Quel que soit le matériel qui est raccordé aux port le système doit respecter les
exigence de la norme CSA C22 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.
Primary rate interface
Each T1 interface 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 registered
Channel Service Unit (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 CSU.
