Cisco MGX 8850 Multiservice Switch Installation and Configuration
Release 1.1.31, Part Number 78-11223-03 Rev. B0, May 2005
Chapter 6 Card and Service Configuration
Configuring Frame Relay Service
Configuring Frame Relay Service
This section first describes how to configure the FRSM card, lines, and ports, then describes how to add
connections. The descriptions are for the CLI execution of the tasks.
MGX-FRSM-HS1/B
Features
• Up to 200 data connections
• In addition to data connections, support for
–
LMI according to ITU-T Q.333 Annex A and ANSI T1.617 Annex
D
–
OAM messaging
• Total card throughput of 16 Mbps
• Choice of the operating card as either X.21 or V.35
• Maximum of 8 Mbps per line
• Choice of DTE or DCE mode for each line
• Maximum frame size of 4510 bytes
• One-to-one mapping between a logical port and a physical line
• Support for metallic (internal) loopback (ITU-T type 1)
• V.35-specific alarms (in addition to standard alarms such as LOS, and
so on)
–
Inactive DCD and CTS signals in DTE mode (red alarm)
–
Inactive RTS signal in DCE mode (red alarm)
–
Selected line type (for example, through the cnfln command on the
CLI) and the attached cable are incompatible (red alarm)
–
Disconnected cable, such as a disconnect at the far end (creating
LOS, a red alarm)
–
No cable attached (a red alarm)
• Support for ANSI/EIA/TIA-613-1993 and ANSI/EIA/TIA-612-1993
Eight-Port FRSM
• Eight-Port FRSM Fractional FRSMs support a single 56 Kbps or
multiple 64 Kbps user-ports (FR-UNI, FR-NNI, FUNI, and Frame
forwarding) per T1 or E1 line.
• Channelized FRSMs (AX-FRSM-8T1-C and AX-FRSM-8E1-C)
support multiple 56 Kbps or Nx64 Kbps user-ports per line up to the
physical line bandwidth limit.
• Bulk distribution for T1 only through the MGX-SRM-3T3. See the
“Service Resource Module” section on page 6-60.
• Redundancy support: the MGX-SRM-3T3 can provide 1:N redundancy
for T1 or E1 operation if the FRSM uses an SMB-8E1 back card.
• Supports OAM Loopback non intrusive test.
• Supports zero CIR service.
• Standard ABR (TM 4.0 compliant).
• Class of service (CoS) mapping.
