Table 13—Data Card Types (continued)
822060 SRU Card Provides 10 port RS-232C/V.24 interfaces. Supports synchronous and/or
asynchronous data ports from 300 bps to 38.4 Kbps.. Supports DS0-A, DS0-B,
V.14 and X.50 Division 3 sub-rate multiplexing format. SRU card ports can also
be multiplexed with voice traffic on an ADPCM engine (up to 19.2 Kbps data
circuit in 24 Kbps ADPCM channel). The 822061 SRU card provides equivalent
functionality as the 822060 except the Idle Pattern has been changed.
822160 SRU Card Functionality equivalent to 822060 SRU card. When used with 822060, increases
the SRU port density per IMACS system beyond the current limit of 60.
822460 SRU Card The 822460 SRU has 4 DB-26 female connectors. Supports synchronous and/or
asynchronous data ports from 300 bps to 38.4 Kbps. Supports DS0-A, DS0-B,
V.14 and X.50 Division 3 sub-rate multiplexing formats. SRU card ports can also
be multiplexed with voice traffic on an ADPCM engine (up to 19.2 Kbps data
circuit in 24 Kbps ADPCM channel).
822560 SRU Card Supports 10 RS-232E synchronous and/or asynchronous data ports from 300 bps to
38.4 Kbps. Supports DS0-A, DS0-B, V.14 and X.50 Division 3 sub-rate
multiplexing formats by hardware instead of software. The configuration is
controlled via local terminal or remote NMS. The SRU offers lower delay and
increasing throughput. SRU card ports can also be multiplexed with voice traffic on
an ADPCM engine (up to 19.2 Kbps data circuit in 24 Kbps ADPCM channel).
Supports CSU, DSU and OCU loop backs.
822860 BnR
Concentrator Card Provides concentration for time slots containing diagnostics from remote IMACS
units. Multiplexes up to 8 ports of Bit-7-Redundant (B7R) or B4R formatted data
channels from up to 8 different DS0s onto a single, asynchronous channel at up to
38.4 Kbps. Data on the aggregate channel is in SLIP format and the interface is
RS-232.
823160 FRAD Card Frame Relay Assembler/Disassembler provides encapsulation for HDLC/SDLC or
Async ports up to 38.4 Kbps. Transparent/Sync up to 38.4 Kbps. This card
concentrate up to 8 non-frame inputs into 2 data streams at 56Kbps or 64Kbps.
Total of 10 ports may be assigned to input (FRAD) or output (concentrator) ports
based on configuration guidelines. Access to this card is via on-card RS-232 or
through DS0-B over T1.
824160 and 822460
OCU-DP Cards
BRI Card
The 824160 (5 port) and 822460 (10 port) allows provisioning of DDS services or
consolidation of DSU traffic as DS0-A or DS0-B. Interfaces directly to DSU at
speeds up to and including 64 Kbps. Does not support BCH error correction,
performance monitoring or operation in CSU mode (used only for back-to-back
OCU-DP ports). Emulates an 8247 for existing system compatibility. Each port
may be connected to a DSU/CSU operating at 64, 56, Switched 56, 19.2, 9.6, 4.8 or
2.4 Kbps. DSUs can be local to several thousand feet distant to IMACS based on
speed and wire gauge.
OCU-DP Card 8249 The 8249 is a 2 port OCU-DP card that provides interfaces for provisioning of
DDS services or consolidation of DSU traffic. Supports DS0-A or DS0-B sub-rate,
56K, 64K and Switched 56Kbps DDS. Supports BCH error correction,
performance monitoring or operation in CSU mode. Secondary channel operation
can be enabled if desired. Optional error correction for inter-IMACS circuits.
