  Back to Carrier Access/Transport Products



Telmar delivers a wide range of space efficient, economical and manageable TDM multiplexing platforms that are ideal for consolidating T1 or E1 connections in cramped CPE and collocation environments. The company’s Wide Bank 28 (WB-28) provides standards-based M13 multiplexing at a dramatically lower price point and higher port density than traditional M13 solutions, while the TransAccess platforms (TA-200 and TA-155) also offer the option of integrated connectivity onto the SONET/SDH transport network at trunk rates up to OC-3/STM-1.  The products support a modular approach to redundancy – reducing downtime and permitting hitless maintenance options for 24/7 service reliability.
