Overview of the CABLE-16TDM-R3OL3=
The CABLE-16TDM-R3OL3= is a high-density TDM (Time-Division Multiplexing) interface cable designed for Cisco routers to bridge legacy telecom systems (e.g., E3, T1/E1) with modern IP networks. It supports 16 channels of E3 (34.368 Mbps) or fractional T3 connectivity, enabling seamless integration of high-capacity voice and data circuits into Cisco’s ASR or ISR platforms.
Key Technical Specifications
- Connector Types: BNC (E3/T3) on the network end and DB-68 (male) for Cisco chassis integration.
- Compatibility: Optimized for Cisco ASR 1000 series routers and ASR 9000 aggregation services routers.
- Signal Support: Handles E3 (34.368 Mbps), T3 (44.736 Mbps), and channelized T1/E1 via software configuration.
- Cable Length: 1 meter (3.3 feet), ideal for rack-to-rack or intra-chassis deployments.
- Standards Compliance: Meets ITU-T G.751 for E3 and ANSI T1.102 for T3 pulse shaping.
Common User Questions Answered
Q: Can this cable replace older TDM cables like CABLE-16TDM-R1EL3= for E3 circuits?
A: Yes. The CABLE-16TDM-R3OL3= is specifically designed for E3 and T3 applications, whereas the R1EL3 variant focuses on T1/E1.
Q: Does it require external clocking or signal regeneration?
A: No. The cable leverages the router’s internal TDM clock synchronization, ensuring stable timing up to 180 meters (with repeaters for longer distances).
Q: Is it backward-compatible with T1/E1 equipment?
A: Yes. When configured for fractional T3, it can split bandwidth into 28 T1 channels or 21 E1 channels.
Typical Use Cases
- Migrating E3/T3 leased lines to IP/MPLS networks.
- Connecting legacy SONET/SDH equipment to Cisco routers.
- Supporting high-density PBX systems in large enterprises or telecom carriers.
Installation Best Practices
- Use 75-ohm BNC terminators to prevent signal reflection in E3/T3 setups.
- Monitor CRC errors and jitter via Cisco’s TDM management tools.
- Avoid coiling excess cable to minimize electromagnetic interference (EMI).
Where to Purchase the CABLE-16TDM-R3OL3=
For guaranteed performance and compliance, purchase the CABLE-16TDM-R3OL3= from authorized suppliers like [“CABLE-16TDM-R3OL3=” link to (https://itmall.sale/product-category/cisco/). Third-party cables risk impedance mismatches, leading to signal degradation or packet loss.
Why Certified E3/T3 Cables Are Non-Negotiable
During a carrier’s network overhaul, a team used uncertified cables for E3 circuits, assuming cost savings. The result? Persistent clock slips disrupted thousands of voice calls until the CABLE-16TDM-R3OL3= was deployed. This reinforced my belief: TDM isn’t obsolete—it’s precision-critical. Certified cables ensure timing accuracy, which generic alternatives can’t guarantee. In legacy migrations, every microsecond counts.
