Interconnect Port Networks with Fiber Optic Cabling
DS1 CONV-Remoted Cabinets
The distance between the DS1 facilities and associated equipment room
hardware and cabling is a maximum of approximately 200 circuit miles (322 km)
for analog voice and 500 circuit miles (805 km) for digital (no analog voice
stations).
NOTE:
These limits for DS1 remoting is the maximum distance between any 2 port
networks with either direct or switched port network connections with a
TN1654 DS1 Converter Circuit pack.
Digital public network tie trunk facilities provide the end-to-end connectivity
between the port networks. For either type of port network (PPN or EPN), a
TN1654 DS1 Converter circuit pack serves as the port network interface to
the DS1 facilities. As a PPN interface, a TN1654 DS1-CONV can reside in
either:
As an EPN interface, a TN1654 DS1 CONV can reside in an expansion control
carrier (in any port slot).
DS1 Cabling within the Local Port Networks. Use the running list that
accompanies the upgrade equipment to determine which cable connects where.
The following paragraphs only provide conceptual information about wiring a DS1
Converter interface either to an expansion interface or to a switch node interface,
not step-by-step procedures.
NOTE:
It is important to label every cable installed.
A cable connects each DS1 CONV either to the appropriate TN570 expansion
interface (for a direct connection to another port network) or to the appropriate
TN573B SN Interface (for a switched connection to another port network).
NOTE:
These cables usually connect to TN570 expansion interfaces (already
installed) for direct connections between the new PPN and either 1 or 2
EPNs.
On the DS1 CONV side, a 4C retainer binds this shielded cable to the DS1 CONV
port connector. On the EI/SNI side, a 4B retainer binds the cable to the EI/SNI port
connector. The DS1 CONV-to-EI/SNI cable also provides a piggy-back connector
enabling subsequent access to the public network.
