Routing carrier links to the Carrier Remote IPE site
A carrier link connecting the system to the Carrier Remote IPE can use a
private or a public T1 or E1 network. The carrier link can consist of one
to three T1 or E1 carriers.
A carrier link terminates in a telco demarcation point and from the telco
demarcation point; carrier links are routed to the intended
telecommunications equipment. The distance between the system or
Carrier Remote IPE and the first T1 or E1 repeater, the CSU, or the LTU
should not exceed 200 m (655 ft). Therefore, the system and the Carrier
Remote IPE should be located within 200 m from their respective telco
demarcation points and the first repeater boxes. The actual distance is
DIP-switch selectable on the Local and Remote Carrier Interface cards.
Note:
Remote IPE equipment is used to connect the Local and Remote Carrier
Interface cards to CSUs at a distance of 32 ft (9.75 m). Install this cable
kit, if applicable, between the telco demarcation point (CSU) and the
Local Carrier Interface card at the local site and the Remote Carrier
Interface card at the remote site as a preinstallation procedure.
Route twisted pairs for T1 or E1 carrier links from the telco demarcation
point to the carrier equipment. Use standard cable routing procedures to
prevent cable exposure to possible damage from contact with machine
and human traffic. Terminate the twisted-pair wires with 8-pin modular
plug. If coaxial cables are used, they must be terminated with BNC-type
connectors.
Note:
must be set on the Local and Remote Carrier Interface card to 75 Ohms.

and SW8 for E1 carrier impedance of 75 Ohms.
Selecting the Local Carrier Interface card slot
The position of the Local Carrier Interface card depends on the type of
system installed at the local site. The system determines in what type of
module the card will be housed.
