VLAN capabilities
When equipped with an Ethernet interface,
RIC-E1 and RIC-T1 transparently connect remote
LANs and VLANs over unframed E1/T1 links,
utilizing the full E1/T1 bandwidth. All of the
above mentioned interfaces are easily
interchangeable thanks to the modular design.
Operating full duplex at a rate of 2.048 Mbps or
1.544 Mbps, respectively, the RIC-E1 and RIC-T1
have a range of 300 meters (1,000 ft) from the
G.703 equipment. They perform a diagnostic
loop test in compliance with ITU V.54 standard
(loop 3) local analog loop (LLB). The bridge
loops are activated by the DTE interface or by a
strap jumper on the PCB.
The RIC-E1 and RIC-T1 support receive, external
and internal clocking options from G.703
equipment.
The products are available as standalone units
in lightweight enclosures, or as cards for the
ASM-MN-214 rack. The ASM-MN-214 can hold
up to 14 hot-swappable converter cards,
allowing mixing and matching any combination
of card types.

The SPD-703-1 rate and interface converter
transfers between the G.703 interface and
other data communications interfaces.
The SPD-703-1 codirectional converter converts
the ITU G.703 64 kbps codirectional interface to
V.35, V.36/V.11, X.21/V.11, RS-530 or V.24.
Operating full duplex at a transmission rate of
64 kbps, the SPD-703-1 has a range of
800 meters (0.5 miles) from the G.703
equipment. It has a built-in BERT complying with
the V.52 standard that provides fault isolation
capability with the activation and monitoring
performed via the front panel.
V.54 diagnostic capabilities provide local analog,
local digital and remote digital loopbacks. These
may be activated from the front panel or via the
interface control signal.
The SPD-703-1 is available as a standalone unit
that can be mounted in a 19-inch rack, or as a
card for the ASM-MN-214 rack.
