Carrier Access SNMP 1.3 Features, Functions, and Options, 1.4 Dual T1/CSU Network Interfaces

1-2 9/24/01
3.072 Mbps of synchronous bandwidth capacity for connecting customer premises telecommunica-
tions equipment to public and private network DS1 services. An Internet or router V.35 port may be
configured for up to 1.5 Mbps on one T1, while all 24 voice channels are terminated on a second T1.
1.3 Features, Functions, and Options
The Access Bank II SNMP combines the functions of an intelligent CSU/DSU, digital access &
cross-connect switch (DACS), and channel bank in a single product that includes the following stan-
dard features, functions, and options.
1.3.1 Standard Features
• Dual T1 ports with integrated diagnostic ESF CSUs
• 3.08Mbps total available bandwidth
• V.35 DCE data port (to 1.536Mbps)
• Drop and Insert (D&I)
• DS0 Digital Cross-Connect System (DCS)
• Command line interface (CLI) for loca l or remote mangement.
• RS-232 Command Line Interface and optional Remote Monitor program.
• Embedded SNMP agent supporting MIB-II and standard MIBS for T1 and V.35 via a
TCP/IP and 10base-T Ethernet connection
• 115 Vac to -48 Vdc Power Converter Cube
• Standard 25-pair female telephone cable connector
1.3.2 Software Programmable Functions
• Drop & Insert (D&I): 1 T1/CSU with 1 T1/CSU D&I port
• 2 T1/CSU DSO Digital Cross-Connect (DCS) with three frames maximum (0.375ms)
T1-toT1 delay
• Bandwidth allocations of voice and data
• ESF to D4 (SF) and D4 to ESF conversions for PBXs with T1 interfaces
• Time of day DS-0 mapping to optimize voice and data utilization
1.4 Dual T1/CSU Network Interfaces
Because the dual T1 network interfaces supply over 3 Mbps of useable bandwidth, the Access Bank
II SNMP is able to demultiplex the primary incoming T1 signal into 12 or 24 analog telephone cir-
cuits for connection to voice, facsimile, and high-speed V.34 modems, leaving the secondary T1 port
