4203 T1/E1 IMA Uplink Module Port Connectors
The 4203 T1/E1 IMA Uplink Module supports eight operational T1/E1 ports, each
with an RJ48C, 8-pin, unkeyed, shielded connector. The 4203 uplink module can
be used to aggregate up to four other GranDSLAM 4200 units subtended in a
stack, allowing up to 120 ports in the stack to be managed with a single
Permanent Virtual Circuit (PVC).
NOTE:
The metal shell of the T1/E1 connector is grounded. Pins 7 and 8 of the
connector are not grounded. Therefore, if the cable you are using is wired to
ground the cable shield to pins 7 and 8, you must first obtain a cable with a
shielded plug and connect the cable shields (drain wires) to the plug’s shield. If
your cable has separate shields for transmit and receive, you must ground
both drain wires. You can also ground the shields at the far end, or you can
use a nonshielded cable.
Procedure
To connect to the 4203 T1/E1 IMA Uplink Module:
1. Determine the interface type, and procure the appropriate cable.
2. Plug up to eight 8-position modular plugs into the ports labeled 1–8.
If this is the aggregation unit in a stack, the unit defaults to using ports 1–4 as
the uplink ports. This default can be changed using the ENT-VCL TL1
command. See the
GranDSLAM 4200 ATM Stackable DSLAM User’s Guide
for more information on subtending and TL1 commands.
3. Install the required ferrite choke on all the DSL cables connected to the 4203
T1/E1 IMA Uplink Module (see Installing the 4203 T1/E1 IMA Uplink DSL
Cable Ferrite Choke on page 2-8).
